Demon Realm

The Demon Realm is the homeland of the Demon Clan.

History
Not much is known about the Demon Realm, except that it is the birthplace for most members of the Demon Clan. According to the Lady of the Lake, the Demon Realm was created alongside the Demon Clan by the Demon King, after he was given birth by Chaos.

The Demon Realm is host to beasts of destruction known as Indura, the true form of most upper-ranked demons with seven hearts. However, not all upper-ranked demons can withstand said transformation, while those that can only use it as a last resort due to the costly sacrifice that has to be made. According to Merlin, The Demon Realm is a polluted and corrupted land covered in miasma in which no other race than the Demons can survive in, as all others are prone to rot and decay there, both physically and psychologically.

Originally a vast and chaotic realm, this was conquered and placed under the control by the Demon King with the help of the Ten Commandments.
