Thaumogenesis was the process through which a new being was created as a by-product of a spell. The magical construct acted as a universal price for having the caster's will done, or, as Anya described it, "a gift with purchase."[1]
Examples[]
Jonathan's monster.
In 2000, Jonathan performed an augmentation spell to alter reality and make himself the best at everything. The spell had the side effect of creating a monster which was meant to balance the effects of the spell by acting as the beast of everything. When Jonathan killed it, he broke the spell and reverted the world to its natural state.[2]
Willow's "child of words."
Two years later, after Willow performed a spell to resurrect Buff, it also created a creature who possessed Anya, Dawn, Xander, and Buffy. The creature sought to possess them because it was out of phase with Earth, meaning it lacked a corporeal body. Banishing the creature would only reverse the spell that created it, but the creature would eventually dissipate unless it killed Buffy, which would allow it to remain in this dimension. Willow and Tara performed a spell to make the demon corporeal so that Buffy could fight and kill it.[1]
Angel and Lilah performed a dark spell in the Hyperion Hotel lobby to turn the demon Sahjhan into a corporeal being and force him to open a rift in reality to enter Quor'toth.[3] Weeks later, when some Sluk demons appeared in the hotel, they surmised that the demons were created via thaumogenesis.[4] When other demons and two people began emerging from the rift, they realized that thaumogenesis was not at play.[5]
