Scary demons and super creeps

[Dannyalcatraz]

I'd probably also do undead more like the way the original Dark Sun did- fewer categories, but more variation within a kind. IOW, what worked on this kind of bloodsucker might not work on that kind. Some zombies you behead, others you keep at bay with salt.

Etc.
