The Kadrillian people's leader, within their species, possessed the designation of Lord Council, as was the case with Lon Prador in 1 ABY. He held the title during the invasion of the Kadrillian homeworld in that year. The Kadrillian people were lead by the Lord Council.
The Planet of Kadril comic strip, which debuted in 1980 via the Los Angeles Times Syndicate, marked the initial appearance of the Lord Council title. Archie Goodwin authored the strip under the pseudonym Russ Helm.
