Brightdawn

Brightdawn is a Celestine colony, the only one in its cluster.
Brightdawn has quite particular laws regarding their nobility. None of them are allowed off-planet, and they tend to regard anyone who has their nobility - even as guests - in the same way as kidnappers or terrorists.
If the leader of a house dies, the entire family vote on a new head.
Although Brightdawn nobilty tends to be insular and xenophobic, they have good relations with Clan Gloryheart which has established a permanent storefront and trade mission in Brightdawn’s capital.
