For the role of Sovereign, there is also an established Line of Succession, both in nobility and in civil governments, which the BTU ignores in favor of conflict over established ranking.

heck, we cannot even get the rulers carrying out their primary duty in the 3140s- a time of turmoil! Heir & a spare! The only one that did so was Jessica Halas-Hughes-Marik with 5 children, and even then she was semi-failure b/c she only had one daughter (Elise) having a child though she was not Jessica's designated replacement. Once she reformed the League she should have been arranging Nikol's marriage and spiking her drinks with fertility drugs. Harrison kept his selection of Julian a secret and his intel chief disappeared. Heck, Harrison's intention to make JulianMelissa seemed to behave like Queen Bess, surprising Trillian by making her the successor- who does not have a consort or children after 8 years. She is trying to unify the realm? Well getting married and knocked up give you two events to work PR magic along with the ability to cement ties. I will leave the immoral mess of the CapCon alone . . . the God-King thing just turns things on its head.
The ONLY House Lord who was SMART about an heir was Yori- and its not spelled out as a plan as part of the Drac court politics, its a accident of BTU writing since all the Lords forget the first rule of monarchies. But it ALSO makes the Kanrei dimmer than his coup supposes. While he had the power, he should have force Yori to marry (say a son or nephew . . . ) and be spiking her drinks with fertility drugs! She gets preggers, pops the kid, gets attached . . . and then 3 years or so later the Kanrei takes a hostage/insurance policy. Do what he says or child takes a spacewalk . . . get too far out of line- your expendable since I hold the heir and will be regent.
The Drac court situation SHOULD be one of the most historically easy to model, since succession politics with heirs & in-laws along with regents fills history pages. Just think of the English two 'lost' princes . . . actually, it seems to have happened a lot to the Norman line of kings. But where we have such fertile soil for dynastic maneuvering in the Drac court, it just gets bypassed.
We also with the Dark Ages get 'branch' switches, which is more historically reflected . . . so Hanse's line through Yvonne is done in the FedSuns with Caleb's death (but considering his behaviors, we should have plenty of illegit SDs running around), but the Steiner-Davion line in the Lyran state took back the throne from whoever Melissa came from. With Trillian supported by Roderick, who IIRC is Adam's descendant . . . guess Roderick 'Frost' is Trillian's heir.
Of course, the League is a story on its own.
A Liao killing a Hasek is far from unprecedented. Michael Davion was a Hasek.
Mikey betrayed Max . . . Amanda defeated/embarassed Daoshen and was never part of the conspiracy. The Capellans have been executing FedSuns and Republic nobles/officials they capture- she is just the most noteworthy. What is Capellan for gulag?
