The sub-realm is categorized into four regions: Scintilaria, Galliptis, Syrith, and Vinlar. The regions vary in size, and all spread to the edge of the sub-realm before dropping off into the Silulis. Each region has its own unique geography features and ecosystem, with many hosting a variety of creatures. All of the regions are ruled by the Dekn Neo-Emperor, from his home in the capital of Taveril'domaine.
The skeleton of an ancient super volcano that had since hollowed out, leaving a wellspring of thousands of inactive and malformed ethric crystals behind. This massive cavern is home to multiple thriving Dekn communities, including the hold city, the Scintilarium. Various plant-like organisms dwell within the dormant volcano, illuminating the caverns and thriving off of the remaining ethric energy.
- Gatiem: Mining town. The oldest mining settlement in Scintilaria.
- Vesva: Mining village.
An expansive desert region of grey metallic rock and sand. Many Dekn communities have grown up and continue to thrive here. The region is also home to the reptilian Vlykinian, who dwell in the desert. Human-Dekn hold city of Laen. Laen is one of the few Dekn strongholds to have both Dekn and humans; it is a huge, technology-based city structured around cybernetic advance, and includes numerous U.M.E.E.C. bases and a massive entertainment district (Zuwiggy's!).
- Trounmark: Small city. Includes a library, a marketplace, and a post office.
- Loosek: Small mining village. Includes a blacksmith and a general store.
- Savesilegro: Large town of metal and rust, with a surplus of blacksmiths. Produces a lot of old-fashioned weaponry and armor, for those who cannot afford U.M.E.E.C. weaponry (or do not wish to support U.M.E.E.C.). Also includes a general store and a tavern.
- Anget: City. Includes a library, a tanner, a marketplace, and a theatre.
- Pascor: Mining town.
- Oasis Underguard: Town. Includes a marketplace, a jeweler, a stonemason, and several farms.
- Qavad: Small village. Includes a bookstore and a grocer.
- Vas: Small mining village. Features a prominent jeweler.
- Merkava: Mining town next to Vas.
- Samael’evri: Town. Includes a stonemason, a tanner, a marketplace, and several farms.
- Enoby: Small city. Includes a stonemason, a jeweler, and a tanner.
A frozen wasteland of black ice. Snow storms in this region are next to blinding, and in some places, frozen ethric fluid causes sinkholes into dark caves, full of deadly creatures known as Shivurs. Between Syrith and Vinlar, there exists an endlessly repeating waterfall where ice is constantly being made and melted; these are known as the Falls of Vinrith. Due to the harsh conditions of Syrith, there is no "hold city" in the region, and few settlements.
- Pickno: Village. Includes a post office and a tanner.
- Scors: Mining village. Includes a stonemason and a tavern.
A region of heat and fire located in the middle of Syrith. This region exists due to failed experiment which attempted to create an alternate power source for the Dekn; the area now draws in all the heat energy from Syrith, causing it to be fiery wasteland. Travel is almost impossible without the proper equipment and protective gear, and there are no settlements or inhabitants (with the exception of the Gaspools).
- Dekn Barons/Baronesses: rule over smaller individual towns (and villages), like a Mayor.
- Dekn Counts/Countesses: rule over the larger towns, and minor cities.
- Dekn Lords/Ladies: rule over the cities and moderate the other rulers in the court.
- Dekn Masters/Mistresses: Have place in the court but do not rule over land; rather, most have their own castles or towers.
- Dekn Emperor/Empress: The Emperor rules over all regions and is the final word in decisions by the lower ranks. They serve until death or they or overthrown, in which case the duel winner, or the next available Master/Mistress, is crowned. Only Masters and Mistresses are allowed duels with the Emperor.
- Shivurs: Beetle-like creatures from Syrith that live in the underground caves and feed off of those unlucky enough to fall in. They bury themselves in their victim's back and then force their legs and pincers through the torso, allowing it to use the body like clothing, as the back remains exposed allowing them flight still.
- Caulbats: Large moth-like animals that fly around Vinlar. They aren't naturally vicious, but when angered they will explode violently and use their bones as shrapnel. From their corpse, a new Caultbat will rise, like a phoenix.
- Duubs: Fat cow-like creatures that live in Galliptis. Their faces are uncannily similar to humans; the eyes and nose and mouth do not seem to be in their natural spots or in natural shapes. They can be harvested for their hide, or their milk.
- Sloamin: Creatures similar to hairless dogs, with flat faces and no snout. They are common in Galliptis and hunted for their meat. They are carnivorous and cannibalistic.
- Jurgensyn: A large snake-like anteater horse-looking hybrid. Dekn are capable of taming and riding them at speeds of up to 79 m.p.h. They feed on the various fauna found in Galliptis and are typically very docile. If threatened, spikes will emerge from their backs, which they can shoot at their attacker.
- Erucs: Frog-like creatures made of a stone-like material. The bigger ones are more solid while the smaller frogs are more gravel-like in makeup. They feed off of rocks as their biology only requires their stomachs to be full, rather than nourishment being required. They make loud honking noises when threatened and live mainly in Vinlar.
- Sivols: Worm-like creatures that snake their way around the Scintilaria region and feed off of the fauna within the cave system. They are typically docile but can be angered and will attack by spitting a very noxious poison at the attacker.
- Gaspools: Round creatures that draw in super heated air, then expel a very toxic gas that can ignite. They resemble round rocks with holes, but are actually sentient and very soft (despite lacking any features besides the openings in their body). The reside solely in Vinlar.
