It's no big deal, really— —just an ancient paranormal creature more powerful than you and all of your Teenage Creature friends AND
Apparently, this being did somebody's ancestor a favor, like,

Now, this Ancient Creature isn't unreasonable; he realizes that popping up out of nowhere after half a millenium could be considered "unexpected", so he's giving you a few days to get things together, but he warned you that after that? He would be forced to take measures considerably more…

IWATC is a narrative-focused urban fantasy RPG where it doesn't matter how strong your werewolf is, or how fast his vampire is, or how beautiful her fae is…what matters is how these characters feel, what drives them to do things, not how inherently capable they are of accomplishing them. What keeps the viewers of Buffy or Teen Wolf or any other young-adult urban fantasy show coming back every episode? Is it the Monster of the Week?
