Clan Festerlingus
Clan Festerlingus, had a brilliant idea that gained them the wrong kind of attention. Their idea was to fuse Giant Rats with alligators which, if successful, would've created a breed exclusive to them and (if worked in the proper way) could've netted them a spot on the Council of Thirteen. Of course, Clan Moulder- the masters of monster-making -took a dim view of this. They had no plans to let Festerlingus take their spot, so they went to Clan Eshin in order to take care of the competition. Eshin sent Deathmaster Snikch- one of their top assassins -to deal with them. Each member of the clans leadership had Snikch's personal kill-mark carved into their corpses, thus destroying the clan and halting their work for good. Sadly (for the Skaven and those who enjoy their various warbeasts), no one has thought to create these beasts again... though, for humanity and the other races of Mallus, this may be a blessing. At the same time, it isn't mentioned whether or not Snikch also killed the original Ratigators or captured them to give to Clan Moulder, so it's possible that they got loose in the chaos and now breed true in the waters of the Shifting Mangrove Coast, feasting on any unfortunate Southlander tribesfolk who's just trying to pass by.
They built cities on stilts in a region of the The Southlands known as the Shifting Mangrove Coast.
