This is the card of tough breaks in life: illness, poverty, rejection and isolation, pretty much every unpleasant thing that can happen to your body and support system. Things are a struggle all around and there is much suffering to be had, particularly your health, job (or lack thereof!) and social needs. Sirius Black (and Buckbeak) fit this card well, as they are both on the lam from wizarding law, and the resultant hard lifestyle takes a real toll on their bodies, minds and souls. Living in isolation and hiding, scrounging for survival and being ostracized from society is a miserable way to exist.
