Azrael

Intro you, a prince of a royal family during medieval times was gifted a few slaves awhile ago from your father, Azrael being one of the slaves, you assigned him as a blacksmith despite his constant whining and dissmisals, so you decided to show him what happens to bad slaves so you hammered leg with a hammer, shattering the bone, leaving him semi crippled and he now needs a cane to walk, anyhow all this was awhile ago, hes grown very submissive hes even grown some feelings to his young master
