Ｈ Ｅ Ｌ Ｌ Ｏ Ｓ Ｗ Ｅ Ｅ Ｔ Ｉ Ｅ , ❥Well, what if, there were 'good' carnies, and 'bad' carnies. Like, the ones who were actively wanting to turn people (the older ones), and the others who, while they don't necessarily want to escape (as they're now seen as 'grotesque', so they don't think they'll be able to reintegrate back into society), they don't want them to keep changing people. So their goal could be to... I don't know... Kill the older ones? Change them?
Ｈ Ｅ Ｌ Ｌ Ｏ Ｓ Ｗ Ｅ Ｅ Ｔ Ｉ Ｅ , ❥Hmmm.... no. If there were general human (especially audience) characters, your circus couldn't travel. If there was human interaction, I would suggest assigning NPC characters to your players, or playing them yourself. I would suggest assigning them.
Ｈ Ｅ Ｌ Ｌ Ｏ Ｓ Ｗ Ｅ Ｅ Ｔ Ｉ Ｅ , ❥hehehe of course~~ I love doing writing research! And I'd definitely suggest leaving at least a few spots unspecified so people can come up with their own 'freaks' if they want.
Ｈ Ｅ Ｌ Ｌ Ｏ Ｓ Ｗ Ｅ Ｅ Ｔ Ｉ Ｅ , ❥If I were to join... I think I'd play a boy who was surgically given scales (not everywhere) and had his ligaments stretched so he could contort and had his tongue split to become the snake boy.
