Yuni

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.

Returning her sister's charm and revealing her fate allows Yuni to move on (although she'll return as a ghost next year if the PCs don't break the Willowshore mindscape before then).

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.

The ghost laments its fate, forcing each living creature within 30-foot area to attempt a DC 25 will save. On a failure, a creature becomes Frightened 2 (or Frightened 3 on a critical failure). On a success, a creature is temporarily immune to this ghost's frightful moan for 1 minute.

Yuni cries out in pain as a ghostly tiger appears to rip and tear at her body, only for additional ghostly tigers to appear and do the same to all creatures in a 30-foot emanation. Creatures in this area take 4d6 slashing damage (DC 25 reflex save).
