If you want a guild with former Vanguard players you might try looking or posting in the guild forums.
RIP Vanguard may all Gods curse Daybreak for its murder!
I often think that if things had gone just a little differently for Vanguard that we might all have been playing it together for the last few years, instead of being here waiting for Pantheon. I honestly wonder how many of ya'll I would have run into. Or maybe I did and you attended one of my events back in the day :)
