“This your boat?” Gavin asked, still disoriented. He was seated on a bench next to a skinny man with white hair and beard, big eyes, half clothed. All of the men down here were skinny and half clothed, all drinking water or tearing into hardtack. All wearing chains. All watching him.

“Yes, my boat. The Bitter Cob, I call her, for how she’ll leave your nethers raw. She belongs to me, and now you belongs to her. Serve well, Guile. For if this old girl goes down, you go down with her.”

The other end of his manacles snapped shut around the oar.

“Gunner…” Gavin said, warning.

“Captain Gunner, Number Six. Or you get a whipping.”

“Orholam damn you, don’t you know who I am?!” It had been almost two decades since Gunner had worked for Gavin. Maybe time had changed him too much for the man to recognize him without his rich clothes.

Gunner grinned. “He who asks, ‘Don’t you know who I am?’ is the one who doesn’t know the answer. But here’s the thing, Gavin Guile. I’m going to give you the opportunity to find out.”

“Not Gavin,” Gavin said defiantly. “Dazen. My name is Dazen Guile.”

Gunner threw open the door and daylight poured in. “Whatever guile you use makes no matter to me. You’re Galley Slave Six. Third row, middle seat. But don’t worry, you row strongly and obey alacritously, and you’ll get a head seat in six months. Good to have goals, ain’t it?” He grinned toothily. “Boys?”

Gavin said nothing. He didn’t resist, for in the open door he’d seen something worse than bondage. In the dim near-night of the reeking cabin, he hadn’t noticed: colors were always muted by darkness. But with the opening of that door, with the sky and the birds and sails, and the pure puissant light that Gavin had been waiting to soak up to use to break these chains and escape, he saw something worse. He couldn’t split the colors from that pure white light. He couldn’t split the colors because he couldn’t draft the colors. He couldn’t draft the colors because he couldn’t see the colors. The ignorant speak of subchromacy as color-blindness, when it really is only color confusion.

But Gavin was color-blind. All the world was gray. It was as Gunner had tried to tell him. In one instant, everything that was special about Gavin Guile had been stripped away. He not only wasn’t the Prism anymore, he wasn’t even a drafter. The door to the deck slapped closed, and chains rattled through the handles, trapping Gavin in a blacker darkness than any he had ever known.
