The Strange Aeons Adventure Path draws to a stunning conclusion! Arriving in the alien city of Carcosa, the adventurers must sever the links that bind Carcosa to Golarion. In wandering the parasitic city the characters navigate the frozen ruins of an elder thing city, deal with accursed partygoers in a reflection of an Azlanti city, and encounter a mute musician who can help them find their way in the maddening streets of lost Carcosa. Can the heroes keep Carcosa from drawing Thrushmoor into its amalgam of stolen cities or do they risk waking the unspeakable nightmare that stirs in the depths of Lake Hali? They must break these links--or Golarion is doomed to greet the King in Yellow.
