The Herald's Prison is split between a shattered abyssal cavern and a surviving tiled prison interior. A massive rune-covered disc and a ring of pale pillars dominate the exposed cavern, while broken walls connect it to more controlled halls containing additional columns, ritual markings and a dark circular alcove. The two halves create very different movement problems within one map.

For Wrath of the Righteous: Herald of the Ivory Labyrinth, the site serves as a prison deep in Baphomet's realm. A GM can stage part of the encounter around the open ritual ground, where characters have room to maneuver but little protection, then force movement through narrow ruined connections into the intact complex. Broken edges and surrounding void make careless positioning dangerous, while the pillars provide intermittent cover. It also works as any planar prison or fractured ritual fortress where ordinary architecture has begun to collapse into something less stable.
