The bickering almost drowns the sound out but Aydin (and Aydin only) is certain he heard a twig snap. Turning around, he sees a humanoid figure standing motionless in the underbrush behind him, obviously aware of his blunder and looking anxious.

The creature looks relatively human. He's naked, standing a little shorter than six feet with strong arms and a stout body. His skin is a ruddy brown and although he's completely bald his arms and chests are covered with thick hair. In his left hand is a club, little more than a large tree branch, and in his right is a sizeable rock.

Aydin effectively has a "surprise round." What does he do?
