First Mention: WB2014 Lord Crush - Part 5
Improcerous is Unit of Bullyclub, possibly a Natural Ally, speculated as a very short unit, perhaps very wide and long, but shaped as a pancake, and possibly with a flat skull as well. Lord Crush killed one which was described as the biggest improcerous he’d ever seen. WB2014_Lord_Crush_-_Part_5
Inprocerous is defined as having little height. As Bully clubs in the Real World are used as blunt instruments to strike malefactors on the head, it is consistent to think that one of their Natural Allies would already be flat, or impervious to being struck upon the head.
