Mainly a first concept for my OC

After an accident while fooling around with transformation magic, wich left him irreversably with a dragons arm, Umbris has learned that no matter how gifted you are with your magical abilities, you should not solely rely on them all the time.
After some major growing up, as well as getting used to his new leg, he found his profesion as a Tinkerer and Inventor wich he backs up by working as a Black and Goldsmith after he figured out that the claws are the perfect tool to make engravings.

Background story for my oc is as you see also still full of holes but im working on it.
