Imperium is a good group of folks - this was not their decision - they are providing us with a way to remain as a group. In game we will wear the Imperium clan tag. Imperium is built as a series of militias, with each militia basically running itself as long as they follow the rules of the Imperium as a whole.
As the Duchy of Wessex, we will still communicate here. Although a bad example for us Americans who know a bit about the revolutionary war, we are like the Hessians. We fight under the Imperium banner, wear the uniform of the Imperium, are loyal to the Imperium as long as those duties do not infringe on our loyalty to the His Majesty, but keep our own internal organization and customs. We are basically *on loan* until His Majesty recalls us.
At least that is how I see it.
