Crypts of the Immortal Fortress (Patreon)

Beneath the Immortal Fortress are a number of small dungeons, tombs, crypts, and oubliettes. As the fortress itself is still inhabited and the residents know better than to explore these lower areas, they remain generally unmolested, with the entrances of the more dangerous areas under guard in case anything should creep out.

These particular crypts were considered inconsequential until a planes-hopping sage showed up with a map indicating something important within – so if you can get into the fortress, getting to the crypts themselves shouldn’t be too hard of a task.

Behind the scenes, this is actually a redraw of a small crossword puzzle posted during the Alternate Reality Game that was played online leading up to the Stream of Eyes event where they announced the upcoming release of the two 5e Waterdeep books this autumn.
