The “akum” are the “huge birds, toothy of maw” that live far to the north of the center of the world, ridden by nomadic warrior tribes. This one is distinct, though: it has a beak like the toothless birds, but has fingers like the akum. She’s wild, and about the size of a modern horse. The akum-rider tribes might see these as unnameable, but I bet there are a people who considers them prize mounts.
