From publisher blurb:
Amidst the dismal, rain-drenched realm of Storm’s Path lies the sprawling laboratory and fortress of the demon princess known as Aldinach, the Lady of Change.
Aldinach would be considered mad by anyone else’s standards, but by her own measure she is a tragically misunderstood artist. Each day, she labors at her craft with single-minded determination, and transforms the bodies and minds of her victims into terrifying new shapes. The truly pure and virtuous are her favorite prey of all, and she frequently sends her servants out in search of beings worthy of her artistry. The twisted and broken remnants are either brainwashed into servitude or are left to freely wander Storm’s Path once Aldinach tires of them. If the Lady of Change is in a generous mood, she may even return a creature to its original world, where its warped soul inevitably pulls it towards those it knew in its former life.

An introduction to Aldinach, her background and her lair.
Roleplaying tips, tactics and suggested minions.
A full stat block (CR24), with lair actions, regional effects and a madness table.
