A Bahro on the Volcano

Bahro, meaning "Beast People", is a derogative term used by the D'ni and other Ronay for non-humans. It is related but not identical to the term Ahrotahntee (Book-worlder, alien).

In Terahnee, the name was another name for the Relyimah slaves. The same name was used by the D'ni for the original (non-human) inhabitants of the Cavern, whom they displaced when they came to Earth.

Yeesha calls them "The Least", and in the game of Uru the explorer discovers several totems belonging to the Bahro. Little is known about them at this time, but they are seen in the ending sequence to Uru climbing up the volcano and into the center. Bahro screams can also be heard in the Cavern from time to time. There are indications that the Bahro were at one time being hunted for sport.

It has been speculated that Bahro might also be another name for the lowest of the classes in D'ni, but this remains speculation. Other than by the name and social status the different Bahro do not appear to have been related.
