Consort of the Lich Queen (Pathfinder)

From publisher blurb:

On a blasted rock, floating in the farthest reaches of the Maelstrom, a lonely figure scans the horizon. Will nobody come rescue Horarion, the Lich Queen's former lover? A group of bold heros could benefit greatly by travelling to his crumbling manor house. Can you offer him eteral release from his solitary prison?

Salvation... by the sword!

While this book is written as part of the Dungeonlands setting, it would work well as a drop-in area for most any fantasy realm. Inside you'll find all you need to run this unique setting, all the background information and encounters to challenge any party of level 16-19 characters, plus new NPC's, critters, traps, and magic.
