Pŵer Dyfaiad

Pŵer Dyfaiad (Power Patriarchs) are a class of ruling Patriarchs the live on the mythical isles of Arallfyd that have domain over Theocratic City States that dot the islands. However it is much more complex than simply being the figure head, as they are the vessel for which the elemental power flows from and becomes strengthened into a usable force.

Etymology
Pŵer is a direct word meaning "Power" and is pronounced as Poo-er.

Dyfaiad is a created word meaning "Family Ruling" and in this scenario, it means a Patriarch. It's pronounced as Duh-fai-add.

Role
Dyfaiad are hereditary clan members of a ruling tribe, who are responsible for maintaining the Cyswllt, a crystal that holds a certain Power within it. Each planet with a substantial Ceidwaid presence requires a Cyswllt in order to have their powers magnified to the point of being useful.

Dyfaiad have their life force tied to the Cyswllt and there are lengthy procedures to take prior to one's death, to ensure the transaction of life force from one to another is smooth and won't endanger the crystal.
