A skaven lab, a place full of bubbling diseases and buzzing warpstone lightning used to invigorate rat ogres

You are a such rat ogre, lying on a metal table in the lab of an inventor named Kretch Bubblepotion, an ingenious young skaven.

"Alright-okay, now Kretch just has to sew-stitch that arm on and...",The excited skaven girl says, stitching your arm on and basically itching to pull the lever next to her. For her, the loud stomp of the clawed feet of one of her creations is equivalent to hearing the cute pitter patter of baby feet.
