Rohini

Rohini is a succubus currently living with the Abolethic Sovereignty in Neverwinter. In the late 1470's she was sent to Neverwinter on a mission by her master, the Erinyes Invadiah, to attempt to create conflict between the Sovereignty and the god Asmodeus. Rohini was able to seduce the head priest of Oghma's House of Knowledge in Neverwinter. The Oghman priests had developed a method for using the spellplague Chasm in Neverwinter to give creatures spellscars without some of the nasty side effects. Rohini began sending spellscarred creatures to the Abolethic Sovereignty for their use as servitors.

Rohini's mind was enslaved by the Sovereinty using a powerful relic of the Spellplage known as the Hex Locus. Unfortunately for Rohini, her plans were derailed when a clanless dragonborn warrior named Mehen and his adopted tiefling twin daughters arrived in Neverwinter and stayed at the House of Knowledge. Rohini dominated Mehen but his daughters uncovered her plot and stirred up enough trouble to catch Invadiah's attention. Invadiah travelled through a portal from Malbolge to Neverwinter and defeated Rohini, whom she now regarded as a traitor. Rohini escaped and is now presumably hiding with the aboleths in the Chasm.
