Put upon, somewhat depressed, and not at all thrilled with the machinations of certain Verminlords, Rittichik Thing-Fixer is a Warlock Engineer with three goals. First, train up enough new Acolytes to allow Clan Skryre to replenish the numbers being depleted by the current Skaven offensives occurring throughout the Realms. Second, keep as far away from Vizzik the so-called Prophet of the Horned Rat as possible, a being he does not trust, suspecting his motives may go much further than even the Great Horned Rat suspects. Finally, third, inspire just enough loyalty in his trainees that when they do choose to make a move against their higher-ups (which, with Skaven, is inevitable – after all, that is how promotions within the Great Clans occur), they do so against any Warlock who is not Rittichik.
What he really wants is to be left alone with his favorite past-time, repairing broken Clan Skryre machinery and trying to recreate devices lost to time (and internecine warfare). His current goal is to somehow create the Skaven equivalent of a Steam Tank, having seen such a machine in action. Alas, Arch-Warlock Spizzik has taken a liking to Acolytes trained by Rittichik, and (against his wishes) has put him in charge of training further spawnings of new underlings.
This irritates him to no end. He is (most recently) often seen stalking around Vexchik Spire, the custom-modified jezzail he uses for a musket canted back on his shoulder as he lights up one of a number of truly noxious cigars that he is often seen smoking, his hammered-copper Warlock armor stained and corroded from years of mis-use.
