The Gardener

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.

Releasing the nereid and allowing her to leave this place (or, alternatively, killing her) allows the Gardener to move on to the afterlife.

When a ghost is destroyed, it re-forms after 2d4 days 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.

A creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.

The ghost stares at a creature it can see within 30 feet. The target takes 9d6 void damage with a DC 37 basic Will save.

A creature that fails its save is also Stupefied 1 for 1 minute.

With a touch, the ghost attempts to drain a living creature's life force. It makes a ghostly hand Strike but deals no damage on a hit.

Instead, the target becomes Drained 1 for 1 day, and the ghost regains HP equal to half its own level.

If the Gardener's next action is to cast a 6th- or lower level spell, reduce the number of actions to cast it by 1 (minimum 1 action).

The ghost cries out in pain and anguish as small objects and debris fly about in a 30-foot emanation. Creatures in this area take 9d6 bludgeoning damage, subject to a DC 37 basic Reflex save.
