While created as part of licensed material, it is not part of the original Buffyverse, but its own developed story.

Thessaly "Thess" Maclay Rosenberg was a Slayer[1] and a witch daughter of Tara Maclay and Willow Rosenberg in an alternative universe where the sun had been nearly blotted out.[2]

After Willow's and Tara's disappearance, Thess sought Buffy Summers,[2] who trained the Potential Slayer[3] and continued her mothers' mission of saving the world by unblocking the sun. In the battle to conclude the ritual, Buffy left her status as a Slayer, activating Thess.[1]

Behind the scenes[]

  • In the non-canon novel series The Next Generation, Willow instead had a daughter named Frankie Rosenberg, who is also a witch and a recently called Slayer. Coincidentally, both Thessaly and Frankie were already predetermined to each be Willow's daughter when they were first pitched to writers Casey Gilly and Kendare Blake by their respective publishers.[4]
