Rin

Rin is bound to the Willowshore mindscape and can travel anywhere within its borders.

A typical ghost can stray only a short distance from where it was killed or the place it haunts. A typical limit is 120 feet. Some ghosts are instead bound to a room, building, item, or creature that was special to it rather than a location.

When a ghost is destroyed, it re-forms after within the location it's bound to, fully healed. A ghost can be permanently destroyed only if someone determines the reason for its existence and sets right whatever prevents the spirit from resting.

Rin transforms into the tailless form of a specific small human. The tailless form can't be altered and resembles her fox-like humanoid form.

A creature damaged by Rin's burning touch must succeed at a DC 25 will save or become cursed. During a cursed creature's moments of triumph, they become limned with spectral flames that punish their allies. Whenever the cursed creature scores a critical hit, each ally within their reach takes 1d6 persistent fire damage as the cursed creature's hubris sears them. This curse has an unlimited duration.
