Who I am
A search through a vast battlefield, through endless corpses, would have perhaps taken weeks, and maybe even longer with just a single person, but with Nate's vampire senses, he could hear any heartbeat among them; in other words, there wasn't the need for him to check each one individually.
Still, the stench of the blood was even getting to his nose now that he was no longer fighting. He had to make sure to hold himself back.
Originally, he had planned to make it so the survivors would help him on his search to make it easier for him to search. After all, there were bound to be a few who would be close to death or need emergency medical care.
He had already sent one of the survivors, who was in good condition, to head back to the ship, to grab some medical supplies, and return as soon as possible, but the rest of the survivors he had found were unwilling to leave his side.
