Watchers in MCU

[coldnightingale.livejournal.com]

I know in comics there is Uatu and other Watchers. But in MCU we kinda didn't see them yet, Stan Lee's particulary suspicious cameos notwithstanding :) So are there any cool fics playing with watchers or something similar? It doesn't have to be the main theme, just they should play role big enough , not just two lines in the middle of 100k epic, you know?

So recs, plz :)) Thanks in advance.
