Depends on the guards. Aedion could fight off 6 of the king's guards at once, so it depends on how skilled the guards are.

I’m betting on Aedion

Definitely Aedion, he can take down a lot of people before he’s even injured, he proved that in Rifthold

Aedion 👀

Not to be the stickler, but Chaol and the 12 guards

Aedion

Aedion. I'm sure he has won in fights that were more difficult than this during his time as a general. Not to mention he is not even human.
