The Prison of Lights is a location in The Shrouded Isles, on the island of Kinir. Though it formerly housed other spiritfolk, it later become dedicated to hosting a single prisoner known as The Warlord. An alternate prison on the island of Azhel is used instead.

The inmates were either devoured or corrupted into mindless beasts under the Warlord's influence. Over time he as well lost his sanity eventually becoming The Abyss, a monster that knows only consumption. It fears the light, but the lanterns filling the prison that were meant to keep him in check burned out long ago.
