A spectral locomotive known as the Ghostlight Express carries wayward souls through the mists of death towards Druskenvald — a strange realm caught beneath an eternal night. When the journey goes catastrophically wrong, the adventurers find themselves stranded in Wickermoor Hollow, an isolated valley filled with restless dead, wicked hags, ravenous monsters and communities whose strange traditions may be every bit as dangerous as the creatures beyond their doors.

The Crooked Moon is a sprawling folk-horror adventure inspired by dark folklore, Halloween legends and classic horror stories. Rather than simply moving from dungeon to dungeon, the characters journey through forests, villages, lakes, forgotten places and unsettling communities while uncovering the secrets of Druskenvald and the powers manipulating its inhabitants. Superstition matters here, curses have consequences, and the heroes' own histories can become woven directly into the unfolding story through the campaign's Fateweaving system.

Expect exploration, mystery, strange humour, colourful characters and plenty of horror as a very unusual group of heroes attempts to survive beneath the ever-watchful gaze of the Crooked Moon.
