Utopia

Background
Utopia is known by all as Zero's true realm, where he resides along with other fallen good sages. After Book 2 not many others are allowed in Utopia since Zero split the planes of realms and moved Utopia.

Utopia is actually split into two parts High Utopia, and Low Utopia. In the Low area is where Zero resides and is where he can watch from the Heavens. High Utopia is where sages go after they have died, or ascended and reside there where they cannot see the mortal plane but live in harmony and peace.
