While he refers to himself as "Master of Warpstone", "Leader of The Pack" or simply "The Brain", his teammates only call him Squeaky, very much to this skaven renegades' discomfort. However, he doesn't seem to have a better place to go and sticks around with the team. He also brags about having an unlimited amount of warpstone at his disposal and since quite a few of his teammates are rather curious about it, no one considers getting rid of him anyway.
As if to prove he doesn't make the warpstone story up, he actually started mutating after only three games, growing some nasty little horns. When someone jokingly called him "The Horned Rat", he did not even object to that...
Squeaky became the first true casualty the team had to suffer. In the first season's
closing match, he got killed by a Dark Elf blitzer, with the apothecary too unsophisticated to save the fragile body. Skaven anatomy is not for everyone.
