Gresilda

Gresilda is the antagonist in the 2-part Haunting Hour episode "The Most Evil Sorcerer". Gresilda is an evil sorceress who used to be Margolin's apprentice, until she challenged Margolin to a magic duel. Gresilda had lost the battle and was left trapped inside the forest of timrod. Gresilda was first shown saving Sara and Ned from a beast as an old creepy woman. She revealed that her creepy disguise was used to scare off enemies.

When Sara had removed Margolin's amulet from his neck Gresilda was free and was ready for another battle with Margolin, but without his amulet Margolin's magic was useless and was transformed into a dung beetle by Gresilda.

After Gresilda had released Margolin outside as a dung beetle permanently she started to act like Margolin (but worst). Gresilda was then tricked by Ned into smelling sleeping potion then Ned remembered the spell Gresilda was performing (when his eyes were taken away and were being put in a jar right next to her.) and had put Gresilda into a deep sleep, but Sara revealing that a kiss can break the spell. 100 years later Gresilda was still under the sleeping spell until a hiker came up thought something was wrong with Gresilda and started to give her CPR. Gresilda woke up furious and shocked the hiker.
