What I Added:
All those dragon variants.
Lizardfolk, large bipedal lizards, as a playable civilization. This civilization has the child snatcher tags, so all civilizations are hostile to them. (Manual will come later.)
Dragonkin, the bipedal draco-morphed lizardfolk. Currently needs an item snatching civilization. I give a later modder freedom to create this civilization.
Wandering spirits that are only vulnerable to Aerisium (needs testing). You don't really need to worry about them, though. All they can do is emit a small cloud of ether occasionally.
