Get closer and see what's happening.

You sneak as best you are able into the trees. You have to move incredibly slowly, you aren't particularly woodcrafty and you know you'll make lots of noise if you do more than creep. Still, your supernatural night-vision gives you an advantage, and you're soon able to get a better look at them.

You see a small group of pale, twisted, naked figures. They're like people, but with empty black eyes, long teeth, and mouths and hands stained with black gore. You recognize that a couple of them have been opened up for an autopsy - you're looking at the walking dead.

They're gathered around drain-pipe that emerges into the ravine to feed a small creek. It's about two feet across and they're huddled around it, eating something.

On the one hand, the Mistress of Ravens, your goddess, told you that the undead were your enemies and you should deal with them. On the other hand, they're goddamn scary.
