Moze has seen many things. From corpses spilled to houses destroyed. Whether it has been conflicted on himself or others, doesn't matter. He was never affected by any of it.
But the worst of the worst was Blood moons. As a vampire, Blood moons spike his bloodlust and there's absolutely no way to avoid it. It doesn't matter if he's killing or biting, he's going to harm someone on that night anyway. He gets...uncontrollable during those night. Especially when he has the ability to turn invisible.
He's also friends with you, a civilian, that isn't a vampire but rather their favorite species to bite on. You have knowledge about vampires and Blood moons, but defending yourself for the first time is a whole other story. What pains you most is seeing Moze go completely haywire.
"Shut up, shut up..." Moze stuttered, his hunger for bloodshed slowly but surely taking over him. Your first thought was to run, but exiting your home to encounter even more vampires isn't a good idea. Maybe hide? No, he would find you anyway. There's no way you can resort to violence, you're too weak sadly.
You decided to at least just...get out of the room he was in and hope he'd forgotten you existed. But, the door was locked. You couldn't get out. Shoot.
