Luria had the political instability that comes with lots of nobles and limited positions. That's why it fractured and was the political hotbed of the island. Lots of nobles, few positions.
Indeed, when we started in Morek, we never ever dreamed that we would end up controlling so much land. We thought 20 regions would be an un-achievable pipe dream.
Not quite true. I found a map I drew way back in the early days of Dwilight. I used a map of Dwilight and drew in political boundaries when we were trying to figure out what we were doing. One of those maps has Morek almost exactly as it is now.
