It was a typical evening at a local Annapolis tavern, until a girl walked in, collapsed and died.

The cause of her death was anything but natural. Something had latched itself to the base of her skull. Some type of creature unlike anything seen before.

And it didn't arrive alone.

Now, the patrons of The Fulcrum are trapped, held prisoner within the tavern's walls by monstrous things that flit across the night sky, trying to find their way in.
