Rand Ko was a Human male who served Emperor Roan Fel's Empire-in-exile as an Imperial Knight Master. In 138 ABY, he led a group of Fel's stormtroopers in defense of the planet Borosk, which was under siege by forces of Darth Krayt's Galactic Empire. When Krayt's soldiers overwhelmed his battle lines, Ko contacted his Emperor and asked for instructions. He was ordered to retreat but was attacked by a Sith before he could relay the order to his troops.
