Old wrinkly witch turned hot babe by Cthulu
Helgatha is a witch that lives in a hut by a small lake the party discovered. She seems to do a lot of alchemy, and is quite versed. She offered a potion to Atan, thinking his appearance was prophetic and came to her in a dream. She also seems to have some sort of allegiance or relationship with a molten salamander that swam up from the depths of the lake.
After Atan started transforming due to the potion, she became quite beautiful rather than her crusty old self. Her old self can be seen in the image below.
