Korrealis Systems

"Korrealis System regrets this inconvenience."

- K-X12 probe droid before exploding

Korrealis Systems was, presumably a Droid manufacuring company or corporation that, presumably, manufactured the K-X12 probe droid.

Behind the scenes
The company is only mentioned once. The mention occurs when in a non-canon occurance when the player fails to repair two of the K-X12 probe droid resulting in all four being destroyed taking Tanis Venn's life along with him.
