Nether

The Nether is created by Heros. This place is also called as the "Underworld" and there's only two people who lived in this area. When Heros lost the battle in the Början War, he started creating the Nether and he built his own kingdom so he can start over. Heros shared his world to his other alliances from gods and demons and it helped the area improved very well.

Present-day
The Nether stays abandon after Heros's death. No one really knows if there's anything left in that world. People haven't explore the area so it stays very hidden to the mortal world and maybe there might be something hidden in the Nether. Only Sector can access his father's realm and he's the one who took over his father's throne but he doesn't go in the place very much that's why it stays in a preserve condition.
