Parahumans of the Wormverse is a set of fan-decks for the game Sentinels of the Multiverse, based on characters from Wildbow's web serial, "Worm". It's entirely a fan project, and isn't affiliated with either Wildbow or the Sentinels team.
It's intended to be a complete set of decks on its own and isn't tested against the base Sentinels decks.
Assume spoilers for all of Worm, including on this webpage.
