The Avendschrook are demon manifestations of jealousy. They aren't called forth from a 'traditional' summoning spell, but instead must be called forth by a magical trigger, such as a temper flare up. During a fight between Anya and Xander against Willow and Tara, three vials of Videer Dust, containing the Avendschrook, were accidently knock over and shattered. The jealousy demons took manifestation, thriving off of the emotions of the Scooby Gang, who were still reeling from the death of Buffy's mother. The green demon-children tore apart the Summers home, and violently attacked its members.
Buffy initially thought the demons were summoned from a mystical trinket called Ezekiel's Bane, which stores energy created by intense emotional experiences that the owner can then tap into and manipulate. However she discovered only when it was too late that the Bane was irrelevent and that the demons were instead being called forth from the tension between the two rival couples in the Scooby Gang. Rushing back to the Magic Shop, Buffy found Willow, Tara, Xander and Anya possessed by the demons and attempting to kill each other, while the Avendschrook tortured Giles like a helpless newborn. The only way to stop the Avendschrook was to return them back to the vials of Videer Dust. Luckily Giles had one more vial in the storage.
Before the Avendschrook could shatter the last vial, Spike snatched it and summoned the demons to the vial, unaffected by the magical jealousy energies because he was a vampire and had no soul or compassion. Giles tucked the vial away in a locked chest, to make sure the demons would not return.
POWERS + WEAKNESSES
The Avendschrook have the ability to manipulate emotions of people and cause negative energy, which they feed off.
They cannot break free from within the vials of Videer Dust vials; they cannot taint beings that lack a soul (such as a vampire).
