Salt Coast: Jon Kon
Jon Kon often appears as a young lad salt giant or halfling in form, but is a known changeling and will usually appear to folk first as an animal before transforming into a tousel haired boy with a shepherd's crook in one hand and a sling in the other.
If spurred to action, Jon Kon likes to sling acorns that explode when they hit something. As a giant, these 'acorns are the size of small boulders.
