Is the Dark Fantasy one with Rhett still open?
If it is:
~ Are other types of creatures (folklore style) available in this world?
~ How dark is dark? I don't mean like gore or anything like that, just like... how old school folktales can sometimes be a little morbid.
Yes! It's yet to be adopted.
Other creatures and cryptids? I didn't think too far on it because I don't mind a few surprises thrown at me. But my boundaries are drawn with the present world and mortal world. So no time travellers (ghosts stuck in an endless twilight is A-OK!), or religious demon lore, or deities.
The generic demons like succubi, revenants and *races of demons* are fine. Lucifer, Lilith and such are not. Mostly because it's too identical to Supernatural and I've done too many of those back then. (I'm really sorry!)
Dark like, "The Grimm brothers were hunters too, and Disney sprinkled enough altruistic fairy godmothers, cutesy dwarves and friendly blue genies to pull wool over children's eyes."
Imagine if Cinderella's "godmother" was a witch who wanted something in return should she fail to come home before midnight (like Ariel from Little Mermaid). And her sisters went to such extreme measures they did slice off a bit of their feet to wear the shoe. Some editions mention this.
Stuff like that.
But you're free to make up the world history of lores with me! ^^
