Team Plague is the unofficial name for the group of allies Plague Knight has amassed to help him brew the Serum Supernus. Some are familiar faces whilst others are entirely new characters.

Team Plague seem to have a poor reputation in the Valley. Some Plague Minions note that the Magicist is taking a big risk helping them, both Plague Knight and Mona think destroying the Tower of Fate will make them more accepted and in the ending Percy notes he hasn't had any rocks thrown at him recently.
