Atherin has two other animals along with with his horse: a large white dog, which is tied up with his horse; and a brown hawk sitting on his shoulder, explaining the need for the piece of scratched leather. The hawk is not as afraid of people as it should be, and watches the others with strangely intelligent eyes.
"I know a fair bit about Ettins, and I'm surprised that they've seen two. They're usually alone... Maybe these are a mated pair? Er, quadruplet?" Atherin shrugs. "As for how they've kept it secret, well. They have good senses - two heads, you know - so they can probably tell when someone's coming, and do something about it."
