The Citadel
Callum was still weak.
He had fought with Xavier in the past, but he had never felt so weak. If he was not wrong, Xavier used a kind of energy-draining power. As an old vampire, Callum had seen all kinds of powers.
However, he had not heard of any vampiric technique that made someone lose their energy. If such a power existed, the supernatural world would be in chaos. After all, it was incredibly scary to fight with someone who could absorb other people's energy.
The drain from Xavier proved why he was considered the greatest threat in the supernatural world. His powers seemed endless and unknown, and no one could predict his steps.
Sterling, on the other hand, was worried about Callum's health. He never thought too deeply about Xavier's powers because he knew Xavier would not use them against him. It was an obnoxious thing to think.
But Xavier believed Xavier's personality.
