Borays are primitive pig like humanoid herbivores. While they are nomadic and possess but primitive technology, they are now present on several worlds, and on most these, though, they were present before human colonists came.
They are herd creatures who follow their leader blindly. They can to some extent understand other languages but seem unable to speak in anything but guttural grunts. They are not stupid and can be thought the use of some more elaborate tools.
On some worlds, they are a pest, stealing grain and other food while on some others, they have been trained to participate in harvesting and other simple tasks.
