HD has multiplayer and for DS its for street pass/guild card sharing. for street pass it likely doesnt matter, no idea if you can get banned for it on steam version. if you dont use these nobody will see it and you can write whatever. you cant change your guild name tough so you better be prepared to live with it.

no, part of the games point is that you make your own guild and adventurers and make your own story around them.
