Death of the Unicorn
Ruler of Amber
Amber is ruled by an absolute Monarchy. The monarch is the sole ruler, and chooses their successor from among those of royal blood. The current Monarch is accorded the title of King/Queen.
In the event that the throne is vacant, a new Monarch is selected after acquiring the crown of Amber and having three Princes/Princesses of the Blood have sworn loyalty to him/her.
Carl Isidor was King of Amber after he created the current Pattern. Having named no successor, on his death the throne was empty as the next head of state was selected. Hayden was named King after Anastasia, Anahera, and Jacob swore loyalty to him.
