In the distance, a terrifying sight catches your eye. Another zombie, crouched over an arm, blood on his mouth. His jaw is torn, and his skin is peeling. Oddly, though, he's wearing some fairly decent clothes...

Then he sees you. And you see him... And see he's cutting up the arm with a knife?

And then, to make things weirder, he speaks. Fluently.

Oh. Another... cough ...human. Come closer, I don't bite.

...

Bad joke. Still, I'm not brainless. My name is Lucius Vortilus. I was infected... but by a rare strain that only I carry now, that preserves my brain functions and stopped decomposition after a certain point. I've been eating zombies to stay... well, I don't need to eat, but I find it a delicacy. I enjoy some vegetables too.

You're somewhat of a unique human to come across, too. Who are you?
