Looking for a multi-fandom fic

[andromedao]

Of the fandoms I know, 9-1-1, Teen Wolf, Dr strange, and iron man.

I know it is a time travel fic, and we spend most of our time in evan buckley's point of view. 

I know buck is a bound magical and that he and stiles are part of a ritual that sends them back in time to save the world.  That they used the life energy of all the weres left alive to help power the spell. That he and Peter hale were friends and fuck buddies until they could come back to there significant others. And that even though both Maddie and eddie died they came back in time to. 

Any help would be appreciated thank you.
