Precursor Races

The words "Precursor Race" in the TrR context means any uber-high tech alien race that preceded Humanity's expansion into the stars.

As Humanity spread across the galaxy, a significant number of "artifacts" were found, all pointing to highly advanced races developing before humans did. The various types of these artifacts shows that at least a dozen advanced races created empires across the galaxy, but most of them have simply disappeared.

Two of the remaining Precursor Races are the Skinnies and the Bushi (Urbanos Sector).
