Preservers

The Preservers are an ancient race (or group of races), known for transplanting humanoid people-groups from their indigenous planet to remote locations, to prevent "cultural extinction."

They placed several tribes of Native Americans on the world Amerind, who were discovered by the USS Enterprise (NCC-1701) in 2269. The Preservers, known as the "Wise Ones" to the transplanted tribes, also left behind an obelisk, which emitted a tractor beam, deflecting asteroids from the planet.

The name "Preservers" was coined by the Vulcan Science Academy or others in the Federation sometime prior to 2269. It is unknown what their indigenous name was, however their language may have been musical in nature, since musical tones were used to operate controls in the obelisk. 

The Preservers might be the same as (or an offshoot of) the ancient humanoids discovered in 2369 by Prof. Richard Galen and Captain Jean-Luc Picard.
