The Nentir Vale and beyond (D&D 4e)
Zehir is the evil god of darkness, poison, and assassins. Snakes are his favored creation, and the yuan-ti revere him above all other gods, offering sacrifice to him in pits full of writhing serpents. He urges his followers to:
✦ Hide under the cloak of night, that your deeds might be kept in secret.
✦ Kill in Zehir’s name and offer each murder as a sacrifice.
✦ Delight in poison, and surround yourself with snakes.
