Military action
Not an all out war, but a drawn out conflict and fight for power between supporters of the four living cousins of Queen Sarra I, who left the throne without any direct offspring. The conflict lead to assassinations of King Warder I and King Anfrith III, and death in battle for King Andrew I. King Munder II was the last living cousin and died of natural causes in the year 3461 SR, leaving the throne to his daughter, Queen Sarra II.
