Xatrix realm

Xatrix is the realm that Kochaku was sealed in by Kyuseishu billions of years ago, before going onto sacrifice himself (as they usually cancel each other out, but now he'd be gone).

After billions of years, Kochaku finally broke out of it in 1052 during the Universal War arc, when he created the Draxons and waged war and destruction on the universe. However he was stopped by the Lookout Crew and sealed away again with the help of the gods.

Only 10 years later, Kochaku broke out again (as the seal was too weak), during the Holy Apocalypse arc. After a long, and difficult conflict, the Lookout Crew, with the help of all the gods and Existential Seed, sealed him away tightly and permanently. However, in 1125, Ninthalor tore the realm open to allow Kochaku to escape and aid him in taking over existence, in the midst of the Great Universal Revolution.
