You may be looking for another Grand Marshall.

The Grand Marshall was an Ice Warrior officer. He led a mission to alter the orbit of Magnus to make it more suitable for Ice Warrior habitation.

The mission was at first successful, but the Sixth Doctor was able to restore the planet to its original orbit. (PROSE: Mission to Magnus, AUDIO: Mission to Magnus)
