Pathfinder Strange Aeons Adventure Path
You awake in Briarstone Asylum, your mind wracked and memories missing. You must work together to recover your missing time and in doing so, soon discover your amnesia to be but a symptom of a much greater cosmic menace. As you struggle to retain your sanity, you must find allies with the other asylum residents and fight against the monstrosities that have taken over the building and plunged it into nightmares.
Can you defeat the terror that stalks the halls and free yourselves from your prison of madness?
