It comes down to this: carry this pack, push this broom, park this car, bury this body. The Mule Squire (or simply “the Mule”) gets all the shit work. Mules are essentially non-people, treated like valets at best, three-legged dogs at worst. Unlike with the role of Sentry, nobody expects a Mule Squire to ascend the ranks. It’s a role that falls to what the higher-ups believe to be those who have already reached their peak: some dumb-fuck Gristlegrinder or crazy Swimmerskin. It might very well be a false assumption, and a Mule who proves himself is notable, indeed, but the assumption exists regardless.
