The Evil Whisper of Moonbright (system agnostic)

In the town of Moonbright, all is not well. Somehow the town folk are being turned into mindless zombies. The king and queen, and the clerics, want to look the other way and hope the problem goes away. But things have been bad enough already in the town, the population trickling away over the years... ever since the sorceress caused a tragic accident. Now a witch, she seeks revenge on the royalty that cast her out from the walls of Moonbright!

This is a pamphlet sized adventure themed around witches and zombies, with Halloween in mind. Any Fantasy tabletop rpg system that you like will do.
