Hello! I'm Cogs and this is Doctor Stephen Strange, Sorcerer Supreme and Sarcastic Asshole (but that Supreme title is claimed by Tony Stark). He's from Marvel 616, so he's survived Civil Wars I and II, House of M, World War Hulk, the Skrull Secret Invasion. I'm bringing him in from the end of The Last Days of Magic storyline while blissfully ignoring some of the crazier stuff that Marvel's been doing for the last two years.

So, basically as a sorcerer he'll be very interested in this pocket dimension while also (guiltily) enjoying a vacation away from the mess he just finished fixing in his canon. MCU folks-- totally up to you if your character "recognizes" him as Doctor Strange even though he's a different version of the guy. Spooky multiverse shenanigans. Other magical folk in the game-- I'd love to get together and abracadabra! Magical support group?
