The folks over at Dragonsfoot have been putting out top quality material for AD&D longer than I've been kicking around in the online Greyhawk community. This week I'm spotlighting a new adventure available there for free download entitled The Howling Hills. The adventure for levels 10-14, is written by Charley Phipps with cover art by Brian "Glad" Thomas.
This looks to be an excellent addition to the on-going mythos of the ancient wizard-lich Acererak and his infamously horrific tombs. I highly recommend this module even for those who don't necessarily play AD&D but want to add a new twist to their land of Iuz campaign.
Update 4/8/2021: I had to remove a broken link to Glad's art.
