From the description:
Grunj are furry, humanoids standing between 3.5 and 4.5 feet tall. They have proportions similar to humans. Their fur comes in varying shades of black, white, gray, and brown. Most grunj have single-colored fur, but some have spotted or striped markings. Grunj have snouts instead of noses and short, pointed ears on the top of their heads. To humans, the grunj look like humanoid dogs.
The book provides a single race for use with the Runebearer game.
