Revenant

The Revenant is a beast that resides in a ruined Chapel, surrounded by the stone faces of its victims. However, her real base of operations is in a massive, brown and black church with no clock and an extensive graveyard...

The creature hates light and cowers in a magic Light Bulb during the day, but at night the creature is free to roam as it pleases...

It has struck up a reluctant deal with another equally terrifying creature, the Bankington, and they both occupy chambers in the expansive Crypt of the ruined Chapel.

Her and fellow witches Ginger Menace and Galadriel often meet up to swap potions and spells, and bitch about members of government.
