One of the three Miller boys of Malice, Pennsylvania. The Miller boys were known to be bullies by just about everyone, but no one knew how dangerous that had become except little Mikey Maloy.

The summer after Urizen, the Miller boys were playing on the Devil's Right Hand and a small shard of the rock went into Preston's foot. He somehow absorbed or released a portion of Urizen's power and shared it with his brothers. Suddenly, they found they could do things with their minds - like making their teacher almost choke to death.

On Halloween, the boys slaughtered pigs and wore their heads as masks to torment little Mikey. Preston lost control of the evil and began to morph into a monster, but Spawn arrived and forced Urizen out of him.

After that day, Preston was terrified of the dark and unable to leave his home, while his brothers never spoke again.

A place between Heaven and Hell, where a soul could have a second chance at redemption. Souls sent to Purgatory were required to solve a large labyrinth and scale to the summit of its mountain in order to be redeemed. All the while, they would be tested by the sins they had committed.

Purgatory was governed by a being named Jonathan Edward Custer until orders from Heaven closed its gates and turned it into a training ground for the heavenly war-hosts.
