Game concept
Regency Succession Score
From the game's encyclopedia
In a Regency, the next Regent is picked based on which candidate has the highest Regency Succession Score.
If the Ruler of the Realm designates a Regent, they will override the succession order and be chosen instead.
This favors Characters related to the Ruler, especially landless Family at their Court and the politically savvy.
