The Vampire Clan has only had one king's chair from beginning to end, and has only supported one ruler, and that is Cain.
After Cain left the first city, rebellion broke out in three generations.
In order to compete for the throne, thirteen clans launched a holy war.
In ninety years of struggle, no one could ascend to the throne.
God's wrath calmed down the war and floods came.
Ninety years have passed, and Ellender and Sheila have returned one after another, and the struggle for the throne has begun again.
