"Henceforth I'll turn a deaf ear to prattling foliage with its arboreal metaphysics, its chlorophyllosophy. My family tree says all I need to hear."
--Salman Rushdie, "The Moor's Last Sigh"

• The PCs are resting in their favorite inn when a messenger arrives for them. Apparently, an elderly man they once saved recently passed away in his sleep. Moreover, he was quite rich, owning a decent-sized plot of fertile land. He never married and had no remaining blood relatives, and willed that his earthly belongings should be left to the PCs. This seems wonderful at first, when the PCs survey their new lands and servants. However, they may begin to suspect something strange is afoot when they hear rumors that the old man had become raving mad before his death. The reasons become clear when the PCs all suffer terrible dreams haunted by a dark figure on the horizon, and they learn that, as the old man's heir, they've inherited a curse that plagued his family brought down on them by a goblin lich. In order to rid themselves of the curse, they must either disown themselves of their new property or find and destroy the lich and his goblinoid horde.
• The PCs encounter and destroy a particularly powerful ghost, and as they do so it shouts a vile curse at the PC who does the deed. Soon after, the cursed PC receives word that a close family member has taken ill and needs magical assistance that only the party can provide. When they arrive, it becomes clear that they are not facing a mere disease, but the relative is being possessed. The relative's eyes reflect a distant malevolence, and he or she laughs madly at the sight of the PC, saying in a whisper that it's good to see them again. As soon as they exorcize the spirit, the same thing happens to another family member. The ghost tells them the only way to release it is through death of the flesh. Can the PCs kill an innocent relative to destroy the ghost?
• Years ago, the PC's city was ruled by a cruel, evil tyrant. Fortunately, long before the PC's time, he was overthrown by the forces of good and laid to rest in a restricted area of the city graveyard and left to rot. In the intermediate decades, a large oak has grown over his grave, growing dark and gnarled from his flesh and spirit. One day, the thing uproots itself and begins terrorizing the city, possessed in the form of a treant by the spirit of the dead tyrant.
