After reading everything there is to read - consider my interest captured! Very much leaning towards a Jack Frost inspired Sidhe 
I read there will be a limit on the ability to open portals between the two worlds. Has that limit been reached yet? Just wanted to ask since I'd love to have one of his major abilities be opening temporary portals through fern frost.
Excellent! Jack Frost is totally a viable character inspiration .
I think I scared people off portals entirely

Which wasn't entirely my intention since we do need SOME people who can move between worlds. It is still an available power.
IC threads went up this morning so we're technically up and running for in game posting (they're linked all over the place, at the top of every thread really). Also started a
Bestiary type thing in the World Building section which will hopefully help clear up some confusion as to how Fae characters and creatures differ.
For the sake of simplicity there aren't multiple character races I felt it would be too limiting/confusing to try and come up with a list. Instead it is just a grade of how much Fae blood you have.
Sidhe→Half Blood→Fae Touched→Human
That's it. If you're making a PC you are one of those four things. The End. You then pick a flavor or inspiration which represents how your Fae blood manifests. Example: Kyrsa's Azazel isn't a dragon, not exactly. That is there is no subclass of dragons in the world. He's a Sidhe who's abilities have developed in such a way that he can shift into a giant fire breathing scaled beast. Sightings of him have given rise to the myths and stories involving dragons. The other Sidhe and Fae don't see him as a dragon, he's one of the noble Fae. The 'concept/inspiration' section on the character sheet is just for clarification and a quick scan down the character list. There are no subspecies. Fae offspring might end up gaining abilities similar to that of their parents (or many great grand parents) but there's no real guarantee of this (magic and genetics are unpredictable

). Seraphina's kids wouldn't be born and recognized as phoenixes, they're either Sidhe/Halfblooded/Fae Touched but they might have some bird like/fire/regenerative abilities (but they don't HAVE to).
As a general rule
At least human intelligence+humanoid shape and size = playable character. The Bestiary has other creatures that, while intelligent in some way, aren't viable PCs. They are the animals and fauna of Faerie, creatures salvaged from a world long dead. If you think to yourself 'that's really cool I should make a character like that!' then it doesn't belong in the Bestiary, it goes in the pool of character inspirations and one of the Fae characters can be based around it later.
