Alright, I'm super sorry that I'm late in replying. I've been busy. Again :/
But, about your character. There is no guild-hopping. You can put in your history about the fact that your character has been to many different guilds, but finally has chosen one sole guild that befits him. This would be, because, as dewdrop13 has said: this is an RPG group based solely on guilds.
I am sorry if it is to your distaste, but I must be firm to this.
As for normal characters, there will be an app and folder for it. It will be labeled as NPC for now, because as dewdrop13 has said: It would be far too confusing right now at the start of the group.
Please respect and appreciate this.
