Elyos is the Demon World where many powerful beings like Dio, Zero, Ley, and Veigas originate. It is a dimension separate from the worlds of the living such as Aernas and the land of the dead that is the Underworld. There are two major opposing factions within the Demon World known as the Hardliners and the Moderates.
In the beginning, the Supreme Creator gave life to Gods who would be responsible for creating worlds and Gods in charge of destroying the decrepit ones. These are known as deities and demons respectively.
Because of their belligerence, instead of being together with deities in the physical world, the Devildom, Elyos, was created for the demons to reside. When they felt the necessity, the demons traverse through the Dimensional Portals to cause destruction.
There are portals connecting Aernas to Elyos, but they had been sealed after the First Demon War. However, due to Baldinar's actions that lead to the Great Explosion of Kounat, the barrier became unstable and as a result, weakened which allowed these portals to start opening across the world.
The demons inhabiting Elyos are known as the Asmodians and a large majority of them who came upon Aernas hail from this race. Within Elyos are tribes with many of them forming alliances with others sharing similar views and opinions.

Other Elyos tribesEdit
Evil forces that started leaking from the gateways across Bermesiah were discerned by Pope St. Constantino as Elyos tribes. The Arachnids lead by Countess Arachne who invaded île de Frost also came from the demon world. Another demon tribe chasing Rin was lead by a powerful, high-ranking demon whose identity is yet to unfold.
Other demon world lifeforms include fire monsters such as Carbon, spider monsters such as Navarus, shadow monsters such as Fennel, and harpies. These monsters have lower levels of intelligence but are recruited into demon armies regardless due to their outstanding abilities in combat.
It is said that a race of Elves known as the Dark Elves also inhabit Elyos. Like other elves from various dimensions, their lightweight bodies, dexterity, and affinity to magic make them experts in battle however they tend to be very aggressive and despise lifeforms outside the demon world. Despite living in the land of demons, it is unknown if they are truly demonic in nature.
As of now, Rose is the only notable Dark Elf encountered in the story although her troops are of the same race as well.
Trivia is the threshold to the portal leading to Aernas. Located at the end of Elyos, Trivia is a barren region at the edge of a massive floating island surrounded by mountains and several island clusters. All Asmodians wishing to enter Aernas must first pass through this region. Trivia is guarded against intruders by black holes that suck and destroy souls.
Crimson River is a territory of Elyos that nestles the mansion of the distinguished family. The region itself is literally surrounded by a great crimson river which made for a much stronger defense against potential intruders.
Purgatory is the prison of the demon world. It is said that no demon can leave Purgatory unless they are dead. In all of Elyos' history, only Duel has managed to break out of the prison. Purgatory also functions as the boundary between Elyos and the Spirit World. Originally guarded by an Asmodian prison master on the Elyos side and the Spirit Lord Tekarion on the Spirit World's side, the death of the Asmodian prison master at the hands of Duel left Tekarion as the sole ruler of the Purgatory.
Burning Canyon is a territory of Elyos that nestles the mansion of the distinguished family. The Burning Canyon Mansion is a natural fort that is built on a valley with red overgrown bushes that look like they are burning. The Underworld Train service also runs through this region, picking up passengers in the Abyss of Demon World and dropping them off in the Underworld.
- The Asmodians are aware of the Haros demons from the Underworld and even they fear the Bounty Hunters as evidenced by Dio, who chose to flee from Rufus when the Haros targeted Ley in the Wizard's Labyrinth.
- In Grand Chase Dimensional Chaser, Elyos was only ever called by its name in Lime's background.
- Oddly enough, even the Asmodian characters do not mention Elyos in the English voiceovers.
- In Rose's background, Dark Elves are also known for their bright colored hair. However, Rose herself has dark hair.
