High Hall Cathedral - Descent into Avernus (All Tiers) (Patreon)

The combined High Hall Cathedral map set for Descent into Avernus, bringing together the cathedral interior, surrounding outbuildings, and exterior approach into one large playable complex within Hellturel.

Designed to support large-scale exploration and combat across one of Elturel’s final strongholds, this version expands the High Hall encounter area far beyond the cathedral itself, providing additional space for fiendish encounters.

Built to integrate with the wider Hellturel and Elturel city maps, this release combines Parts 1 and 2 of the High Hall project into a single connected location. The catacombs will follow as a separate future release.

Map production support from Lair of Artificer.
