House Tantor was a House Major that used Atomics against House Corrino and they destroyed Salusa Secundus in the 2nd Millenium AG. For that reason the Imperial capital had to be moved to Kaitain. Emperor Hassik Corrino III lashed out against House Tantor, and declared that the family had to be wiped out. The House had been all but obliterated. Shaddam, uncaring, sentenced him to be incarcerated; and sent Hundro on a prison frigate in a heighliner, back to Kaitain. Moritani then mysteriously died as his frigate de-pressurized killing him, the last known descendant of House Tantor.
