I've seen you around, but don't think we've been properly introduced. I'm Dr. Stephen Strange. I used to be the world's top neurosurgeon before an accident destroyed most of the nerve endings and caused muscle damage in both my hands, making them too shaky to perform surgery anymore. So I took up sorcery, instead.
I can use my magic to steady my hands to help with medical emergencies, but it's something that requires full time concentration, so I can't cast any spells at that time. You can put me down as somebody who is willing to help, in a pinch.
