Gra were goatlike herd animals raised by farmers on a number of planets.
They were four-legged mammals with white fur and twin horns atop their head; they were genetically engineered to be hardier and have better survival instincts in the wilderness. Entire herds of frozen fertilized gra ova were sold, to be thawed out and grown by farmers on new worlds.
Farmers raised gra herds on Sulon and Ruusan, among others.
