These are the various dimensions throughout AbyssalCraft. Not all of them have been released yet, so expect them to become available over time.Oblivionaire is said to be the one watching over this place, or his dragon, Asorah. Likely where Coralium originates from.
Dread Plague was unleashed on it, killing all miners and corrupting the peaceful Abyssalnite Golems. The second layer of the Abyss holds lost souls of the living.
J'zahar holds the only entrance to where The Great Old Ones dwell. The Gatekeeper is always watching, and nobody leaves the final layer of the Abyss alive.
(This dimension is unfinished, and only contains J'zahar's temple as a structure)
Beneath Omothol lies the realm where the immortal souls of evil daemonic gods rest, awaiting their reincarnation. The Dark Realm is where living shadows are born, and the last place a living souls should ever visit, as they will face eternal suffering.
