A Dynasty represents an unbroken family line. Each Dynasty is made up of multiple Houses working towards bringing renown upon the Dynasty.
Each Dynasty will have a Founding House, usually of the same name as the Dynasty, which is the first House of that Dynasty. Ruling Dynasty members that are distant by blood to the current House Head may choose to create a Cadet Branch, a new House under the Dynasty. Each House has its own name, coat of arms and motto, usually inspired by the location in which they are founded and the founding character
Creating a Cadet Branch has the following requirements:
- The character must be blood-related to their current House Head
- The character must not stand to inherit any of their current House Head's titles
- The character must have sufficient Prestige
- All ancestors of the character are dead
If a House Head demands the conversion of a House member and the member refuses it will result in the creation of a new Cadet Branch.
The House Head is the leader of a House. House Heads have the power to legitimize bastards, call House members to war and demand that they convert to their Faith. In addition House Heads will get a Hook on all newly born House members and passive Prestige based on the number of members in the House.
The most powerful House Head of a Dynasty will always become the Dynast upon the death of the current one. The Dynast can disinherit and restore the inheritance of Dynasty members, Denounce and Forgive members of the Dynasty, personally claim titles held by Dynasty members and force members of the Dynasty to end all wars against each other. The Dynast also gains Prestige for every living member of the Dynasty.
When character who creates a Cadet Branch becomes its House Head, becoming free from the direct influence of their old House Head unless he or she was the Dynast.
Renown is a resource accumulated by a Dynasty and is used for the most powerful Dynast interactions, unlocking Dynasty Legacies and increasing a Dynasty's level of Splendor. A Dynasty gains Renown for every ruler of the Dynasty who is not a vassal under another member. This is based on tier, which means that a King will give more Renown than a Duke for example. Renown can also be gained by marrying powerful rulers.
Firstly, all renown earned by a Dynasty counts towards its level of Splendor, which determines how well the Dynasty is perceived in the eyes of the world, how much Prestige characters get from being born or marrying into it the maximum long reign Opinion characters can get and how decorated the Dynasty's coat of arms will be. Having a high level also makes it much easier to arrange marriages, especially with Dynasties with a lower level of Splendor. The level of Splendor will never decrease. Peasant Dynasties start at a negative level of Splendor, which causes loss of Prestige for characters marrying them.
Dynasty Legacies are permanent modifiers and unlocks that can be unlocked by the Dynast and affect every member of a Dynasty. Each Legacy contains five unlocks, each costing a progressively higher amount of Renown to unlock.
