Damien moved cautiously through the forest, honing his senses and silencing his steps as he stalked his prey. It was an elk, and by its size, he estimated it weighed at least 600 pounds. He stretched out his hands and focused, attempting to summon the same power he had used before. But as he suspected, he was out of mana.
He had exhausted it all while escaping Beastfall and the little he gained after was quickly used up. The only way to replenish his mana was to drink the blood of a mage.
He had more or less, pieced together how he had become a vampire: it was from the claw, it had been smeared with Elise's blood when he was stabbed and it activated the virus he had taken.
All he knew about vampires was that they were a race of humans who gained mana by absorbing it from the blood of mages. As a vampire grew stronger, they received what were called gifts—unique powers at their disposal.
