Cracks in the Crimson Cage

From the front of the book: Mortal heroes have just foiled a plot to assassinate a god and despoil his realm. The perpetrators’ trail leads to Carceri, an astral prison that detains powerful abominations, disobedient angels, and horrors from beyond the known planes. The only way to find out who’s behind the attack is for you to give chase into the Red Prison... and risk being trapped for eternity with beings feared even by the gods. A three-round Living Forgotten Realms adventure set in Carceri for 22nd level characters. This adventure is a direct sequel to EPIC3-1 The Glorious Hunt.
