Kaelon II was an inhabited planet, the homeworld of the Kaelons. It was the second planet in the Kaelon system.
By 3367 CE, it was common knowledge that the star in the Kaelon system was dying. Nevertheless, the Kaelons refused to leave their homeworld -- believing it to be central to their existence. Kaelon scientists, led by Dr. Timicin, sought to revitalize their sun.
