- National Ancient Studies Research Institute

     The Research Institution of Ancient Studies is a building established in New Helic City, dedicated to finding out about Zi's past. Within its walls are skeletons, artifacts, and other relics from the old world. Some of the animals featured in the fossils are pterosaurs and duncleosteus. Other artifacts include a tablet from the Gurrill Plateau Ruins. It also has a portrait of Dr. D for his fame and contribution to both sides of the nations.

- New Helic City

     New Helic City is the capitol of the Republic. It is one of the largest cities ever seen in the series, and is where Madame President resides during most of her time. The city is home to its own Military Base, the National Ancient Studies Research Institute, and many other famous locations. Its city is filled with festive people that enjoy a good parade when they see one, and celebrate profusely whenever there is a major victory. The city itself is on the coast.

- New Helic City Military Base

     This Military Base is inside of New Helic City, and is shown to hold multiple Gojulas, Guysack, Command Wolf, Shield Liger (White color scheme), and other such Zoids. There is a clear line from the base to the shore in case of sea invasion, and they have a clear view of the Mount Osa base in the opposite direction.

- Number 7 West Block Base

     A military base stationed near the border of the Republican Army. It appears to have no Zoids stationed at the base, and thus was quickly destroyed when attacked by a rogue running Stealth Viper pilot.

- Organoids

     Organoids are smaller Zoids, capable of dissolving into raw energy and merging to the core of a Zoid. The stimulation of the Zoid Core increases a Zoids abilities, in everything from raw energy/power to speed and strength.

     In the beginning of the series, Organoids are of such rarity that many people believe them to be mere myth. It is only people that encounter them, and the Imperial/Republican Army that believe in and have evidence of their existence.

     These creatures are of unknown origin- they never discover if they are created or born naturally like other Zoids, as Organoids do not have a core that supports the life in a regular Zoid. The only thing that is known about them is their present-day abilities to merge to and evolve Zoids, and that they come from ancient times when the Ancient Zoidians were still living on the planet.

     At one point Dr. D mentions that there are myths regarding Organoids, but that in spite of their existance little has been discovered, even from those captured by the armies. He mentions a legend in which when Ancient Zoidians were locked in their capsules, the Organoids sealed along side them retained the memories of their Zoidian companions. He also mentioned that Organoids were known to have a very special bond with Zoidians, and accompanied them wherever they went.

     Throughout the series there are only four Organoids. Zeke (who belongs to Van), Shadow (who belongs to Raven), Ambient (who belongs to Hiltz), and Specular (who belongs to Rease). They show a different level of abilities, as well as maturity and skill level.

- Pods

     According to Ancient Zoidian times, pods have been used to seal not only humans, but Organoids. It is specified in other parts of the Zoids franchise that cores do age, and eventually decay, and so it is assumed that these chambers are required to keep a Zoid Core young and alive over a long period of time.

     The first instance of these pods being used, that was seen in the series, was with the Ancient Zoidian girl "Fiona" and 'her' Organoid "Zeke". It is seen that a large number of cables run to these pods to keep them fully functional, and upon activation, they shatter into many shards of glass after a resounding heart beat pumps life back into the inhabitants.

     Although it is never specified just how old these pods are, they must be hundreds of years at least, to have kept Ancient Zoidians alive for such a long time. Many had fallen into human and military hands, and while the cables seem to be integral to sustaining them, it is seen that the pods can be removed from these cables and transported for a short period of time before it becomes detrimental to their health.

- Prozen Knights

     The Prozen Knights is a unit not mentioned much in the series, but represented by Hardin and her Iron Kong PK. Although it is unclear of the rest of her unit quality as one of the Knights (assuming it doesn't) she controls a number of subordinants, with little regard for their safety.

- Rarehertz

     A Rarehertz; a mysterious pulse that seems to travel, and inflicts Zoids with a type of 'illness'. This pulse affects the systems directly, and causes a Zoid to rapidly malfunction. This malfunction can be anything from off sightings, to complete disability or acts of extreme violence when the Zoid loses control.

     It is explained that Zoids are unable to escape a Rarehertz, but that Pulse Guards installed in most Zoids can at least subdue the pulse. These pulses can spontaneously disappear, and later appear in other areas -- making it impossible to tell where they will strike next, and making them a serious danger to civilians. Some indication can be given to the presence of a Rarehertz as select few Zoids eyes will change color when encountering the anomaly.

- Red River

     The Red River is a massive body of water that runs through the Imperial Continent. It is the home of several bases, and resides on the border of both Helic Republic and Guylos Imperial territories.

- Red River Base

     The Red River base is a large base that sets on ... well, the Red River. It is the first line of defense against the Imperial Territory that resides along the same river, and is armed with multiple Gordos, Command Wolves, and Pteras. The exterier of the base has an aerial launch pad that juts off the side of a cliff.
     Red River has remained in active use throughout the city. It was later used as the first deployment of the brand new Storm Sworders and for the entire time that it has been active, has been overseen by Rob Herman. Rather or not more Storm Sworders are ordered to the base, after the loss of their first two, has yet to be confirmed.

- Satsu

     Satsu is an unpictured city that is supposed to be near New Helic City. It is mentioned briefly during Episode 16.

- Seatl

     Seatle is assumed to be the town where Van first encountered Rease and her large Double Sworder. There was a sign near the town with this name on it, as well as "Dillon Jacks", so we're just running with it. Be aware that it may not be the official name.

     At any rate, the town is very impressive. Filled with large brick houses and a massive cathedral, it sports a very high class work compared to the old west style buildings seen in a lot of other cities. The cathedral is by far the largest building seen in town and has two large bell towers and an incredible stained glass window interior.

- Seatl Ruins

     The Seatle Ruins were first discovered by the Republican excavation teams. It was one of few ruins ever found that had a substantial number of ancient tablets; tablets that would possibly contain information on the Zoid Eve. After the attack on Seatl by the Ancient Zoidian girl the tablets were discovered to be missing from the ruin.

- Security Detachment

     The Security Detachment is just a basic building in conjunction with the Guardian Force and other authoritive forces. It is the location that Guardian Force Fighters will go to be debriefed on their mission and anything that they'll need to know before heading out. It can also assist with providing supplies.

- Sleeper Zoids

     Sleeper Zoids are Zoids that belonged to the Imperial or Republican armies. These Zoids have a black box in place of a pilot, which contains pre-constructed orders for the Zoid. It determines how and when they act, and governs their intelligence in combat situations. Because of this, Sleepers are considered to be an easy target in a one on one fight.

     Among these details, Sleepers are also known to fire on a pilot, while a normal Zoid would not, if it fits into their normal combat criteria. Many will chase down pilots or Zoids that are detected to have unauthorized weaponry or ammunition.

- Snow Mountain

     Snow Mountain is one of the few places referenced in the anime that actually has a frozen climate. The entire mountain is covered in thick fluffy snow, making it an attraction to many.

- Snow Rocket

     A rocket created by Dr. D. It was originally intended to create snow, but the first experiment failed (and just coincidentally lined up with a natural snow occurrence.)

- The Three Guards Unit

     The Three Guards Unit was once made up of the best pilots ever gracing the Empire. They were said to be undefeatable, and noble to boot, always doing what was best for civilians. In present time they are retired from the Empire, only being called out of retirement once, and for a lesser cause. This unit has three pilots: Wagner, Grosscao, and Vipei.

     With only three Zoids it is fairly impressive that this unit receives so much recognition. Their Zoids are three Zaber Fang AT, but are fairly out dated for the equipment and technology known to Zabers today. The intricate designs of these Zoids was only ever seen on one other: The Royal Zaber, implying that these pilots have received incredible recognition from the late Emperor. The unit has two silvers and one gold, each with custom shoulder armor.

     Even after their official retirement the Three Guards were unable to ignore civilians in need. They have hunted down and murdered Imperial soldiers that were known to have caused great harm to their own citizens, and will even attack their former side if they consider them to go against their honor.

- The Valley of Heroes

     The Valley of Heroes is near the City of Wind. It is said that in ancient times, before the Helic Guylos war, hundreds of Zoids warriors would pass through the valley, using it's strange, natural arena-shaped battle ground to prove their strength against each other. Each country would send its strongest pilots to prove their worth in a competition to see who was the strongest.

     Although it was once a battle ground for the greatest pilots on Zi, it has been out of use for a very, very long time. In spite of this its prestigious past remains fresh in the minds of the citizens. When a battle broke out between the Three Guards and Van's group hundreds of citizens gathered along the walls of the valley to cheer on the battle.

- Valley of the Rarehertz

     Although this valley/mountain is never given an official name, it is one of the few places on Zi that is recognized to be inflicted Rarehertz, not in travel; but frequently, across the entire valley.

- Wild Zoid

     Wild Zoids in the Chaotic Century anime are Zoids that have escaped from the army. When this was brought up, it lead us to believe that sentient Zoids can choose to leave the army, if they find the right opportunity. These Zoids are often peaceful, and while they usually won't be inclined to take on a pilot, they rarely fire on other pilots or Zoids unless it's in self defense.

- Wind Colony

     The Wind Colony is a specific colony that resides in the Elemia Desert. It is located on the Imperial Continent, Europa.

     While the Colony seems to be extremely small and humble, the people within it thrive and have a strong sense of family. Most of the buildings have began to decay, or are covered in moss from years of aging, and the surrounding habitable land is used for corn and other fields that help to sustain the people. Beautiful forest and a large oasis surround the living quarters of the colony.

     In the second episode, the Wind Colony is attacked by the Desert Alcabalino gang in an attempt to obtain the Organoid Zeke.

- ZG

     The military term for the Gojulas. This is how it was referred to for the first few episodes before deployment.

- Zoid

     A Zoid is, of course, the main attraction of the series. Zoids are massive mechanical animals, used frequently by the Empire and Republic. Although most are employed for Military use, they are sentient beings, running off of a Zoid Core that contains their mind and memory. Aside from this massive power source, it is also indicated that Zoids have a self-healing ability, and can heal minor damages over a few days depending on how good that ability is. Wiring inside the frame can be reconfigured to increase this ability.

- Zoid Core

     A Zoid core is, in short, the very life and essence of the Zoid. It has been referred to as the "heart," but also contains the mind and functionality. If a Zoid core is damaged the Zoid could suffer mass amounts of memory loss or, if the Zoid is damaged enough will even cause the Zoid to irreparably shut down. In essence, the Zoid will die. When the death of the Zoid originates from the desruction of the Zoid Core the Zoid itself will turn to stone. In a situation where this is a slower process, only sections of the Zoid will be transformed and progressively become worse.

     Throughout the series the Core proves to be a fickle thing. Not only can it fluctuate in power depending on the Zoid's personality, tenacity, and will, but the core can also be merged with Organoids, and even Ancient Zoidians (are supposedly humans) that happen to fuse with the Zoid. It is also noted that these spheres draw power from the Zoid Eve. If they happen to be close to the Eve the Core can completely regenerate a Zoid, or fluctuate massively in power.

     In some instances, when the Zoid is destroyed but the Core survives, it is recovered by the army to be used with other Zoids. In these cases they seem to freeze it with a type of liquid nitrogen for transport. Cores are also known to absorb (or potentially release) nutrients in water, with them being used to develope the strengths and life of many in-developement Zoids that were created by the Empire.

- The Zoid Hunters

     The Zoid Hunters were a group supposedly under the command of Prozen, though this can still be up to debate, as Hiltz at one point acted against the group (strangely before their success.) The group used two "bases", a mobile fortress (the Whale King) and a stationary base that was built into a stand alone mountain, with a landing strip for the Whale King built onto the flat top.

     This group was recognized by the Guardian Force dispatchers and was known to be capturing sleeper Zoids that were left over from the war. It was later discovered that they were using these Zoids for an experiment in which the core would be mutated. Their goal was to create a new type of Zoid, one that strangely resembled the Gun Gyarados. A special separation furnace was used to separate the Zoids from their cores, and the cores were then put into a special chamber where electrical surges would be applied. Most simply destabilized and dissolved.

     At no point were they distinguished to be successful in their attempts. The Whale King was severely damaged during take off and ended up crashing into their base, a disaster rigged up by Hiltz. The entire underground base and the Whale King were completely destroyed, along with any alleged evidence of their objectives.

- Zoid Magnite

     Zoid Magnite is a strange blue ore resembling the same stone that makes up the Zoid Eve. It is used in the revival of some Zoids, and has been seen to be able to revive Organoids who are on their death bed. Rather or not this same ore can be used to revive Zoids is questionable, but the rarity and difficulty of obtaining it would suggest that it wouldn't be worth while to harvest.

     Zoid Magnite has only been found in Mount Osa (in the series), an active Volcano that burns at a temperature of over 2,000 degrees.
