The blood clan was the vampire family.
It was said that the ancestor of the blood clan, Cain, was one of the two sons of Adam and his wife, Eve. Later, because Cain was jealous of his younger brother Abel, he killed Abel. In order to punish him, God turned him into a vampire.
There were a total of thirteen clans in the blood race, and it was said that they were created by the thirteen descendants of Cain. These thirteen clans were divided into three alliances because of different beliefs.
They were the secret alliance, the devil feast Alliance, and the neutral Alliance.
Among them, the hidden Alliance followed an ancient teaching that the blood clan should not appear in the world, or even affect people's lives.
On the other hand, the devil feast Alliance saw humans as blood food and madly appeared in the human world. They used methods such as the embrace to reproduce and disrupt the order of the human world.
