The Sea Witch
Shape Changing Underwater Adept
The sea witch is a creature of legend, whispered about in hushed tones by the nearby sea dwellers. The Merfolk in particular have many stories about him/her/it, as it is rumored it was once a legendary merman of great renown. Now, little is known save that those that visit usually end up never coming back, victims of some gardening project or another.
