Salu Chakat was the captain of the all-tengu carrack Winged Predator. He tried to establish a colony for tengu on the Fernlat's Islet in the Shackles in about 4692 AR but many of them succumbed to a wasting disease after uncovering an ancient ruined structure built from unnatural greenish-black stone. The island has been avoided since then.
