From publisher blurb:
For this realm of Suzerain, we mix gothic horror with dark fantasy to create a Frankenstein's monster wielding a vorpal sword.
Is Nocturne Dracula, or Frankenstein, or the Wolfman? Is Nocturne Ravenloft, Dark Souls or The Witcher? No, indeed not. Nocturne is its own gothic fantasy, holding many classic tropes dear to its heart while striking off in its own direction. Follow the Weave of the Lands and see where it leads you.
The darkness is a friend, a weapon and a mystery.
Hear the midnight song. Heed the nocturne.
Inside, you'll find what you need to create characters in this unique setting, a wealth of background information, a full campaign, heaps of side quests, and stats for all manner of new NPCs and critters
