Scene 8: River Crossing
According to the lore, some rare and powerful vampires like Master Vampires have been known to create weather in small ways like summoning fog. It's nothing that anyone would call dangerous weather. Vampires do occasionally, however, ally with other powerful evil creatures that have various powers. Dangerous weather could be done by such an ally, like an evil Elemental Fusionist maybe, or else it could be unrelated to the vampires.
The Catci return Doc's greeting with overly-friendly waves. Their carts are pulled by some sort of deebee animal species similar to oxen. The animals are reacting skittish because of Polkatain, but they are panicking the way Earth animals tend to do. They answers Polkatain that they live as scavengers, fishermen, and gardeners until they find a place safe enough to settle and establish a permanent farm. Mexico is beautiful but very warm. The humans who live there tend to huddle together in small walled villages where they are not friendly to strangers. There are friendly creatures around, like a psi-pony they know, but these are few and tend to wander around also. Most vampires look like humans -- maybe humans with longer teeth -- but all humans sort of look alike to these guys. The vampires are shape changers who can sometimes become wolves or bats or even small clouds of smoke. These peace-loving deebees do not attempt to fight the vampires, so they wouldn't know how.
