Gargoyles S02E09 - City of Stone (1)

Demona plots with Xanatos to steal one minute of life from everyone in the city, an excuse for how she's lived for over 1000 years. The Weird Sisters appear and watch as the spell Demona casts instead turns the humans to stone during the night, allowing Demona to easily dispatch them as she remembers her history, growing old in fear of humans until offered safe haven in a new castle.
