Ran it once (will run it again), and its a unique adventure that twists the end of a dungeon crawl. I thought the BBEG would be harder, but my players squashed him too easy after taking care of 3/4 relics. Id like to run it again to see if it was a fluke but the relics may have hampered him too much.

I would like to add the maps are horrible if you print or VTT them. Nothing lines up and the wood grain is awful to figure out battle squares.
