Tower of Urm - Descent into Avernus (All Tiers) (Patreon)

The Tower of Urm appears in Avernus only briefly before vanishing across the planes once again. Perched atop an island in a lake of boiling blood, the iron tower serves as the temporary home of the legendary archmage Mordenkainen, drawing yugoloth mercenaries and infernal schemers eager to earn his favor—or his downfall.

The map includes both the exterior view (with balcony for Mordenkainen to address the gathered mercenaries) and an interior, should the players be invited in for a nice cup of tea. Interior is 1 level only.
