In each firmament, the family that was blessed by the Heavens with Sovereign grade would rule it and naturally, they have absolute control in the firmament.

However, in the Barren firmament, the highest rank of a family blessed by the heavens was only Duke grade and it was the Crestlance family, who declared themselves as the Royal family of the firmament.

Nevertheless, if another family gains the Sovereign grade or even duke grade by the Heavens, it would make them a laughing stock in the entire firmament world.

So, the Crestlance family came up with a plan of making all the families that were blessed by the Heavens their subsidiary families. 

By doing so, even if other families gain the 'Duke' status from the Heavens, they could not become the royal family of the barren firmament.
