We took the region to keep the monsters back. I dont think many people actually know what was going on between us but there was no backroom dealings or doublecrosses, Caerwyn made us into an enemy and we were not, we were isolated and willing to work with Caerwyn, they chose to ignore us diplomatically so we did what we wanted for attention. Taking Lowervia was a message to them, work with us, or we will work around you. We are not subordinate, but we are also not the enemy.
