Best place to ask, yeah?

Okay, I've been rewatching The Sound of Drums and End of Time, and I need fic. Specifically, epic!fic where the Master takes up the Doctor's repeated offer to run off with him around the universe.

I've checked Fanfiction.net and LJ, but I'm probably missing several obvious fics that fit the bill perfectly. So, community, any recs?
