Stop stop stop.1. Lord British may not be back in our game, but he IS alive, therefore he is still King. For him not to be King he had to, or has to, abdicate and now to further complicate the issue it seems that -
By having Lord British reappear they have made nonsense of one section of Sosarian lore.
This is just plainly not true. Where are you finding the Ultima Lore for the rules on Kingship? What about the King before British? British himself was practically ELECTED King. He WILLINGLY gave up his power, to leave and protect the shards. He WILLINGLY gave the Council right to rule.
This is not real life, nor is it some other fantasy world. This is Ultima, thus only Ultima should be taken into consideration for the "rules" on Kings or rulers.
