This is just a VERY rough story idea I had that I'd thought I'd share because I lack the skill to write it, so if the premise interests you, feel free to make the story yourself and change things as you wish.
The timeframe is well before the show as we know it takes place, with Octavia just being born and I.M.P not existing yet. The main idea consists of either Stolas summoning Strange Supreme (from episode four, eight, and nine of the Marvel What If…? Series) by accident while performing rituals looking to summon some magical advisor or servant, or the alternative where Strange reaches out using portals/scrying spells, searching through various universes in an attempt to escape his eternal prison, eventually finding Stolas and managing to convince him to summon him to hell in exchange for servitude or something.
As for Strange's role in the story, I think it would be interesting for Strange to form some sort of uncle/protective relationship with Octavia while she grows up while also aiding Stolas with either his magical experiments or royal duties. As for the rest of the story, that is completely open-ended and up to whoever writes it to determine. I just figured it'd be neat to see someone so powerful (having broken time itself in his universe, forcibly changing a reality stone, and casually containing and consuming an explosion meant to annihilate an entire galaxy) interacting with the cast of the show.
This is just a rough idea, and I'm open to anyone writing and changing it however they wish.
