Well, could we remain as an aquilonian mercenary guild and consolidate our power and influence in Poitain? Makes us more flexible then, as opposed to becoming more of an official fighting unit of aquilonia. Being mercenaries gives it more of a flavour, and more RPing scope.
So to put it simply:
`We keep it as a mercenary guild and use our city to spread our influence and have wars with other nation's guilds.`
