Lord Alexsei, Lord Behemoth, and Lord Cecillion were the lords who had exceptional gifts that most vampires fear the most. The three of them both had evil hearts and a thirst for power.
Lord Alexsei had the forbidden capability to control the blood cells of every living thing close to him. Lord Behemoth had this ancient magic that summoned and commanded all beasts from the underworld. Hence, he was called the ruler of the darkness realm.
On the other hand, although Lord Cecilion was the youngest son, he had all things that his two older brothers had. He could control blood and summon the dark beast. Plus, he had the technique of resurrecting the dead without sacrificing his life.
Not surprisingly, Lord Cecillion was the wariest and feared among the siblings.
Lord Behemoth rarely appeared and mostly lived in the underworld, while Lord Alexsei had a fatal weakness. He enjoyed playing with women and easily lowered his guard to the point of being trapped.
