Ylisandroth

Ylisandroth is a lower being of the demon world. In order to survive on this plane, she must obtain energies from others. She uses the black arts to surround herself with admirers and feeds off of them. Ylisandroth approached a Sunnydale student, Brad Caulfield, who was willing to do anything to prevent his sickmother from dying. With magicks and Caulfield's weak breakable mind, Ylisandroth posed as Caulfield's girlfriend Sandra Roth Shipman nicknamed Sandy, and gathered his friends for her necessary feeding ritual.While posing as a human, Ylisandroth followed Caulfield through the day, taking up classes at Sunnydale High, where she befriended Buffy Summers. Not being able to understand why Sandy would hang around a jerk like Caulfield, Buffy thought that Caulfield was using magics to control her after she overheard him talking about wicca candles. Crashing his party that night, Buffy discovered that it was Sandy who was using magic.Severing Ylisandroth's ritual link with her intended sacrifices, Buffy watched in horror as Caulfield and the others fell into a comatose state, while Ylisandroth fled the scene. Calling the Scoobies to fix Caulfield and the others' condition, Buffy went demon-hunting. Receiving a call from Giles, Buffy found out that Ylisandroth couldn't survive on this plane without the energies that she needed from her sacrifices. There wasn't enough time for her to start the ritual over again, which meant she'd have to go back for her sacrifices. Buffy raced back to Ylisandroth's house, but arrived too late, as Ylisandroth had already resumed the ritual, and had captured her friends as extra 'fodder'. Unable break the circuit or remove her friends from the pentagon circle without getting them killed, Buffy removed the fan blade from the ceiling and 86'd Ylisandroth.
