The Possessed (Wendy Redressed)

Wendy is the sister of Vanessa, the Autumn Witch who betrayed her coven sisters for power.  Vanessa also betrayed her blood sister, Wendy.  She sold her sister to demons to gain power, and now Wendy's body is a vessel for Pazuzu, a Babylonian demon (who also possessed Regan in The Exorcist).  The difference is that the demon has footholds in Wendy that cannot be exorcised because of the pact made with Vanessa.  As long as her sister lives, Wendy will never be free.  And even if Vanessa dies, the damage may be too fargone.  The only thing that's keeping the demon in check is Bianca.  Ruled off as a Satanist and heretic, Bianca is Wendy's only salvation.
