I've been trying to find more information on the NPC guilds in game, but can't seem to scrounge any up. My main question is: Upon reaching the proper rank for joining guilds (rank 20?) how limited do things become? But any information on the guilds requirements, benefits, etc. would be welcome (or a link).

For example, say I was a pugilist. When I reach the right rank I'm assuming I can join the pugilist guild, do the quests, get guild marks, and spend them as well. Now, if I leveled up another class like thaumaturge, can I also join the corresponding guild for that class and enjoy the benefit of the pugilist guild at the same time? Or would I have to leave the pugilist guild (and lose the benefits that are exclusive to being in that guild) to join another disciple of war or magic guild?

This question is also aimed at the other disciplines, too. Can you be a master of all the disciple of hand and land classes at the same time, or do you have to pick and choose at some point?

It's sort of a broad inquiry, but I haven't been able to find a source that explains much on how the guilds work. only one disciple of war, one disciple of hand, and one disciple of land, or anything in between. So if anyone can post a link or explain it that would tremendously helpful.
