Kardoa was a planetary body, characterized by its rocky terrain, situated within the galaxy. Following the bombing at the Jedi Temple by a period of three weeks, Jedi Master Depa Billaba, accompanied by her Padawan learner Caleb Dume, journeyed to this planet in order to ascertain whether or not the Separatist faction had established a foothold there. Upon the arrival of the Jedi and the clone trooper battalion under their command, they were met by Separatist forces, which triggered a brief skirmish.
Notably, within the introductory opening crawl of Kanan 10, a factual error occurs where Kardoa is erroneously identified as Kaller.
