Kron

The Kron are an alien race imprisoned within the Twilight Cage. Led by Foreman Krag, they once resided in the same galaxy as Mobius, but were teleported to the Cage in the Argus Event and trapped on a fragment of rock from their homeworld. Like all of the other aliens in the Twilight Cage, they were prepared to wage violent conquest on their homeworld. Upon the arrival of the Nocturnus Clan they were conquered and enslaved by Imperator Ix. (CSE)

The Kron are a simple race of rock-people who were once savage warriors but are now quarry workers and excellent craftsmen. (CSE)
