I'd be really interested in getting something going. If anything just working with the leaders of two (or more) guilds too get some mystery and intrigue into the streets of the world.
You have any info on Sanctuary more from an RP standpoint? Thoughts? Ideals? etc?
(HEY! I should have just clicked the link to your guilds site. Done!)
Now all we need is an opposing guild. Maybe not evil, but darker.
