Asgard and Earth after The Avengers

[kirookshono.livejournal.com]

Hi guys, I'm looking for post-Avengers fics where Asgard and other realm or interstellar powers (like the Kree, Xandar, etc.), see Earth's defeat of the Chitauri and take notice--realizing that Earth is already on its way to becoming a major power in its own right. I'm especially looking for fics with one or more of the following:

1) The Avengers visiting Asgard and conducting diplomacy/discussing the battle
a) Asgardian reactions to Tony's arc reactor

2) A focus on the role of technology in Earth's rise, especially with BAMF!Tony

3) A contrast between Earth's scientific view of technology and Asgard's semi-mystical view

4) Tony/Thor platonic bromance

5) Tony and/or SHIELD studying magic

I haven't been able to find anything of this nature, and I'd really appreciate it if you guys could help me out.

Thanks!
