A long time ago, I approached Genesis about opening a guild in SD. Sure, came the reply, and the conditions such as membership ands skills required.
The actions, if I'd continued at that time would have probably closed one of the loremaster guilds, potentialy the artyisans as the member ship was very low then.
Since then, the number of loremasters in the land has rightly rocketed and its nice to see. Yes, if a SD loremaster guild now does open then members will move from other guilds. As I understand it, yours would not be affected as much as some, as I, Occam etcv are alchemists and not artisans.
