'Apocrypha' means 'those having been cast away'.

A series of creatures and such that will reside in my own form of the underworld.. as it seems, the story that I am working on requires such a place... and I don't feel like ripping other peoples ideas.

Tier 1 (T1) denotes the weakest, lowest of the creatures, Tier 5 (T5) the highest, most powerful ones, and all those in between accordingly. The 'underworld' is ruled by 'shadows' - a dark mist that engulfs all those who enter and reside within it at will. It designates the caste of those who come and go, effortlessly penetrating their souls and morphing their bodies.

The gates of the 'underworld' are sealed by 9 Immortals, it is their duty to guard its gates, which if unsealed, unleashes the 'darkness' into their world.

The 'underworld' also has 'windows', places that one can enter into the underworld. Only select Tier 4 and Tier 5 creatures may pass back and forth, the 'windows' being in various places.
