F!MagePC is doing some magical research around various sites dotting Skyrim (perhaps she's on assignment from the college? It's up to A!A). It's risky, dangerous work so she decides to hire a seasoned warrior to accompany her. Who better than a Companion? Farkas is assigned on the job. He's wary at first because - magic! She thinks he's a dumb brute. They don't start off on the best of terms but as their journey progresses they're forced to depend on each other more and more which brings them closer (in more ways than one *hinthint*) :)

Bonus for Breton or Imperial PC - sizekink
