"Let the Leaves Fall" is a Pathfinder adventure for four 4th-level characters. This adventure continues the Season of Ghosts Adventure Path, a four-part monthly campaign inspired by Asian horror in which a band of adventurers must protect their hometown from supernatural peril. This adventure also includes articles about a local autumnal festival and the reincarnation-focused philosophy of Sangpotshi, new magic items, spells, and rituals to be discovered, and a mix of supernatural monsters to menace your PCs.
