Ehrenfest (Duchy)

The Ehrenfest territory/duchy is currently governed by Jilvester the current archduke.

The territory is bordered by the Ahrensbach, Klassenberg, Frenbeltag, and Zausengas territories/duchies.

History
When nobles from another duchy invade and dethrone another duchy's archduke, a new archduke is chosen from the invaders with the most mana. The territory/duchy and its central city was renamed to Ehrenfest after the defeat of the previous archduke. Succession within the archduke's family is determined by which child has the most mana rather than by age.
