Rat King needs a reliable partner to help him fight through the chaos of New York, push enemy lanes, destroy Guardians and Walkers, and ultimately defeat the opposing Patron. That's where you come in, partner! Fight by his side, watch his back, and help him claim victory for his kingdom. And one little piece of advice: don't go asking the Rat King about his real name... unless you wanna find out just how many rats he can fit in your bed.
