Twilight Cage Inhabitants

A N'rrgal (lower right corner) and the other aliens of the Twilight Cage

The N'rrgal were an alien race imprisoned within the Twilight Cage. Led by the N'rrgal Queen, 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. The N'rrgal soon became bitter enemies of the Zoah, a race of armored giants, and upon the arrival of the Nocturnus Clan they were conquered and enslaved by Imperator Ix. (CSE)

The N'rrgal were a race of green slime-eating energy creatures, existing as either single drones or larger, more powerful and intelligent versions. The N'rrgal Queen was the largest, and thus the most intelligent, of these swarms. In general, N'rrgal resemble slugs. (CSE)
