Just started my reread of Bloodfever and noticed this description of the Shades:
"Shades come in all different shapes and sizes. Some are small and thin, others are tall and wide. They have no real substances. They're hard to pick out from the darkness, but once you know what to look for you can spot them, if you're a sidhe-seer. They're areas that are darker and denser, and ooz malevolence. They moove around a lot, as if they're hungry and restless. They make no noise[...]" etc. LOL
And do you know what immediately popped into my mind?
Does that make me strange? Not really. I think I was already a wee bit strange :P
