Alternatively, you could have a name which is sufficiently simple, flavoured (if not original), and informative.
The Ring of Rogues, for example.
Or: The Band of Theives.
Of course, when you have a rogue guild I\'d imagine that you probably wouldn\'t want to attract the attention of the authorities, so a fancy name might be justified in this case (besides which you\'d get proper rogues and shifty characters joining...People who can ask around and whatnot).
So the question is...Is \"The Rogue Guild\" a roleplaying name or not? On one hand it is simple like traditional medieval guilds, and on the other hand rogue guilds probably were and are the exception of the rule in Guild naming.
Of course, if RPing won\'t be enforced in PS, you can go ahead and name it the \"We will kill you guild\"
