Purgatory

Purgatory is the realm that bridges the Earthly Realm and the Heavenly Realm, everyone that dies has to pass through purgatory to get to the gate and then on to heaven. The purpose of purgatory is to make the transition from life to death easier on human souls.

Appearance
Purgatory is different from person to person usually taking the appearance of what would make the individual most comfortable. Purgatory's default appearance is basically a cloud of white mist that surrounds the soul. The white mist is all that the newcomers to purgatory see before the mist begins to takes it's form.

Lost Souls
Purgatory is full of souls that were either to scared to enter the gate or just rejected by the guardian. These souls roam around purgatory and eventually fade away and degenerate back into Soul Seeds. These seeds are gathered by the Cleaners, who are extremely violent and considered pyro-maniacs because of their obsession with explosions. They take the seeds and give them to the Guardian who deposits them into the gate.
