“What are you planning for Edward, Bertilak?” Fox asked.

Bertilak laughed. “Trying to keep me talking so you can keep track of me?”

Fox oriented on him again and confirmed that listening to the sand around them was effective as a crude sensor.

Bertilak rushed toward him. Fox backed up in time and brought his arm blades down in time to deflect a blow from Bertilak’s mace. He grabbed for where he thought the chain was, connected with it, and pulled, but it slipped out of his hands. Something sharp dug into Fox’s left forearm.

Bertilak’s mace dragged in the sand, splitting Fox’s attention and making it harder to pinpoint where Bertilak and his weapon were.
