No, not the tv show. An AU where supernatural creatures roam the earth and our assassins may or may not be one of them. The Kenways could be a werewolf family, Ezio may have had a run in with a vampire or two in his travels, and Altaïr might face off with any number of crazy awesome, middle eastern beings. And let's not forget the modern kids either - Lucy might be a siren, Desmond an awkward medium that's constantly possessed because his shield are crap, and Rebecca might be an ex-hunter of some sort.

Any pairings are a go-go, although OP has a soft spot for Shaun/Rebecca, Connor/Ellen, Ezio/Leo, and Altair/Maria/Malik. But seriously, whatever the author pleases as long as it isn't underage. And because this is a kinkmeme, feel free to throw in any sort of kink you feel fit.
