Kalonn

Kalonn was a planet-sized droid.

Biography
The droid named Kalonn was built by the Xilan species eons ago for the sole goal to exterminate all life in the galaxy.

The Alliance to Restore the Republic, during investigations about the loss of starships in the Métensis system, found Kalonn. From space, it appeared as a hollow planet with high concentration of metallic components. A team then explored the surface and the ship, only to discover hints of battles.

The droid introduced intself as "Kalonn, the 102st Exterminator", and told the rebels that he was awaken by the crashed ships. Now conscious and willing to finish its mission, Kalonn started its propulsion, but was stopped when the exploration team destroyed its primary energy source.

Behind the scenes
Kalonn was created by Jean Balczesak for the ambiguously canon roleplaying scenario "Dans la nuit des temps" which appeared in the French magazine Casus Belli 66.
