Therra Malevola
Background
The Plot
Therra Arcson had been an annoyance, a thorn in the side of the Circle and other groups since she got her powers. Some direct strikes at her were thwarted by her ability, her friends, and her link to her patron - the one only referred to as the Lady. Multiple groups had failed to kill her or otherwise take her out of the picture.
When she was trapped in a collapse of a Council supply tunnel, though, an opportunity opened up. The mages of the Circle decided not to kill her - oh, no. They'd do worse. They'd destroy her relationships and reputation with her family, friends and the city.
Infiltrating the destroyed Council tunnel, they found plenty of samples which could be used in a powerful ritual - hair and blood, especially. They brought these back with them, weaving them alongside magics into a new body they crafted. This sort of body wouldn't work for them - aside from the raw materials needed, it couldn't house an Orenbangan spirit properly - but that wasn't what they had in mind.
