Clan Pestilens wasn't the only Skaven clan that earned a home in the jungles of Lustria. Clan Spittle (though 'Spittl' is also an acceptable version of spelling) also maintains a home in the wild jungle there. Hunting Lizardmen has become a job for their warriors and "their foes' flayed, scaly skin" is converted into effective armor. Feathers also adorn their shields, helmets (which are the only pieces of their equipment that aren't made of lizard-skin) and certain weapons.
As of Age of Sigmar, Clan Spittle is deceased (thanks due in no small part to Pestilens' diseases). This is proven because the Skaven have developed a severe fear of the Lizardmen and their Slann masters.
