Leechmonger

The corrupted form of the fallen Risaia of Istarel, one of the wards of Maiden Astraea. After she met her death at the hands of three Giant Deprived Ones, Risaia's body fell into a mass of leeches, which feasted upon it. The Fog touched the soul-enhanced leeches, creating the Leechmonger.
