It's the middle of night, and it's dark. There's a chill in the air. Stars, moonlight, articifial lighting, all of it seems to be conspicuously absent.

So where is that patch of even deeper darkness coming from, like a shadow of a shadow? It slips through the air, sensed more by its motion than by sight, creeping closer...

(ooc: for pun theme, a member of shadow galactica as a literal shadow! also, trying out potential for a waking dream; feel free for characters to think they've woken up to find the shadow in their room/wherever they're sleeping - set any scene desired.)
