Precursors
From the Sonic News Network, the Sonic Wiki
The Precursors were a race that lived in the Twilight Cage long before the Nocturnus were brought there by Argus. They are never seen in the game, but they have left items known as "Precursor Tablets" that can be found on all of the colonies, each of the tablets can be deciphered by Nestor.
