Asad's Keep is one of the many crumbling siege towers in the Cairnlands outside of Absalom. It was a Qadiran fortress built centuries ago by the ambitious Taliq Asad who tried to take the city of Absalom. The sturdy keep sank into the earth around the time Asad's efforts failed. Pathfinder Society has a particular interest for the ruins of Asad's Keep.1
Asad's Keep is featured in the Pathfinder Society Scenario First Steps, Part II: To Delve the Dungeon Deep.
