After reforming an adventurer band into a dwarven hold/kingdom with the Dwarven Clans G-reform, I was intrigued when I noticed that I could still switch to an Adventurer Kingdom afterward.

Are there any unmentioned incentives in staying as Dwarven Clans? Such as good events that only happen as that G-reform?
Or do the events just look at the nation tag, allowing you to Adventure to your hearts content?

On that note, do the Adventurer Kingdoms have any neat events you might covet, or is it a mess waiting for your error in picking the reform?
