Folklore & Background for the Liminal Sprite?

[J. A.]

In my last session I used a liminal sprite to baffle and bemuse the PCs, and the encounter became the centerpiece of the evening. It went well enough that the PCs now have the sprite as an ally, so I have a couple of questions about this creature.

First, was this based on any actual folklore, in particular the sprites’ defining curse? It has a fairy-tale feel to it, and I’d like to read the source material if there is any.

I’d also like to know if there’s any game information on the liminal sprites beyond their one page in Bestiary 5. For instance, it’s not specified what exactly happens to a sprite if they’re trapped inside a building overnight, or caught without shelter under the stars. Are they simply prevented from sleeping, or does something worse happen? And is there any additional information on their culture and place in the world?

Very very many of the monsters in B5 come from a particular mythological, literary, prior Pathfinder or other such source, but the liminal sprite was one of the few that came entirely from a B5 author's creativity (chuspiki is another). They are unable to rest if they get stuck, which should have results at least as bad as fatigue/exhaustion that can't be easily removed without sleeping in a viable location.

Awesome dot!

Please, sir, may I have s'more?

Please pass along my compliments to that author--the liminal sprite is one of my favorite creatures from B5, which itself is my favorite Bestiary.

Do you know any other details of the curse? Who or what cast it on the ancestral sprites, and for what terrible purpose? The PCs will be sure to ask about it sooner or later, and while I can develop something passable, I'd love to include the author's own lore if that's available.
