What I'm interested in seeing is if actions committed by a human might garner their attention, both unwanted and if desired.
I suppose you have to consider things from a bigger picture stand-point. Yes, impressive acts as a human might garner the interest of a recruiter from the Angar Rylla, perhaps giving you the opportunity to join the evil space empire. But ultimately, there's only so much a human can do, and usually your actions will be fairly insignificant as a person in the grand scheme of things. When you have storylines where planets are blown up and galaxies are fought over, winning a battle on a planet or overthrowing an evil King or something is pretty small scale.
(For example, I'd never bother introducing Brennus to the Multiverse, and even Sigurd only had one brief encounter due to the WOTW tournament, where he had one small dialogue with the Liason. I may however introduce the Ramor, who are just now discovering rifts on their homeworld which is allowing all sorts of weird shit in.)
Still, you can always discuss it with people.
Also, I think a log would be a good idea, where everyone may have a single post which they update with important Lore regarding their roster in the multiverse with the OP being reserved for grand scale multiverse events and factions. It would be interesting to look back and see what sort of continuity has been constructed so far.
