|Emperor of Mordusia|
House of Orange-Villayn
|First monarch:||Edward III|
|Last monarch:||Otto V|
The Emperor of Mordusia is the monarch of Mordusia. The throne of Mordusia can, according to Mordusian law, only be occupied by a descendant of Emperor Mordus I. Currently the only royal family in the world that can hold this seat is the House of Orange-Villayn which its full title is the House of Orange-Villayn-Rothingren-Traugott-Sayon-Mordus. The House of Sayon-Mordus is the original royal house of Mordusia. The House of Orange-Villayn obtained the title of Sayon-Mordus upon Edward III's marriage to Princess Elizabeth of Mordusia (who's full name was Princess Elizabeth Sayon-Modrus).
Efforts have been made to circumvent the law, installing a "King of Mordusia" which is a lesser title than the Emperor of Mordusia and has succeeded several times. The aristocracy of Luthori and Mordusia have largely ignored claims of the non-dynastic members to the throne of the Emperor. According to records officially, the House of Orange-Villayn-Rothingren-Traugott-Sayon-Mordus is considered to be extinct.
