AV Exploration?Follow

I saw someone the other day who managed to get past the mountains on the west side of AV, and eventually managed to disappear off the edge of the map. I'm always interested in these things... does anyone know how this could be done? Videos, maybe?

No clue man, I tried exploring in losing AV once. (trying to get past the hordies chokehold at IBGY)

I got ganked by 3 wandering rogues and ended up back at the entrance to AV.

Needless to say I was pretty much done exploring for the night.
