Nano I

He awoke face-down in a large field. His head was pounding. How much had he had to drink last night?
He didn't even remember drinking at all. In fact he remembered very little about anything at all, ever. He didn't even know where he was or even who he was.
Something was digging into his leg and he rolled on to his side to investigate.
There was something in his pocket. He took it out. It was the size of a matchbox, but made of seemingly much tougher material. There was no opening anywhere on the box. It was for all intents and purposes a solid lump of some kind of substance.
Except it wasn't solid because something inside it was rattling.
He turned the object over and over in his hand.
