Opening the Portal centers on a ritual chamber overwhelmed by a crackling sphere of red planar energy. The portal dominates the main floor, while branching corridors connect it to fire-lit rooms, a grated work area, storage alcoves and a narrow side study. Those supporting spaces make the site feel like an active ritual facility rather than a single magical circle floating in an empty room.

For Wrath of the Righteous: City of Locusts, the unstable gateway is the obvious objective. A GM can layer defenders through the adjoining rooms, use the tight connectors to delay intruders and reserve the open ritual floor for the decisive struggle over the portal itself. The map also works as a summoning laboratory, planar engine room or occult facility where the characters must reach the dangerous center while enemies exploit the architecture around it.
