Just got Oblivion last week or so but i can't seem to find out who's Grey Fox or if you can actualy see him.Where is he?

Im the Grey Fox 0_0
Follow the theifs guild story line and when you beat it you learn who he is, and what the Grey Fox really is, and what the mask does.
It's really fun doing all the quests too.

If you can't figure it out how to start the quests, look around the Imperial City and read some of the Gray Fox posters. The beggars are a good source of information as well! =D

heh..thieves guild...thats fun stuff. i stole so much junk when I got bored once that i pretty much didnt have to fence anything else at all.
