Author's blurb: This is the 45th in an ongoing series aimed to provide the overworked DM with ready-to run encounters. Will the bold heroes be defeated by the brass guardian or gain access to a dungeon from another reality? It includes a history/background for the encounter, a map, and monster stats. The companion ZIP file contains JPEG versions of the maps (with and without grid), a Hero Lab file, the Word file of the encounter, an .xml export of the monsters (compatible with Fantasy Grounds) and a PDF with character sheets for all the monsters.
