The skeleton at the decks goes by Aria. He has been broadcasting from somewhere underground for as long as anyone can remember. He doesn't talk. He plays. He listens for callers.
Tonight, somewhere in his patch, the bones rattled and a few signatures leaked into the wires. If you're patient, and you know where to look, you can probably catch them. Aria doesn't mind. He likes the company.
Three signals. Three layers. You bring the tools.
