Unidentified Mandalorian commander

During Revan's quest for the Star Forge, he had to journey to Kashyyyk to find one of the ancient Star Maps. Once he has entered the Lower Shadowlands, he finds a Wookiee fighting of three Mandalorians. If Revan choses to help the Wookiee, he will recieve a quest to find, and kill the Mandalorian commander.

Behind the scenes
The only way to find these "invisible Mandalorians", and the Mandalorina Commander, you party members, and Revan must unequip themselves with a weapon, and you must fing an area were there are three dead Wookiees lying on the ground. Once you have killed both groups of Mandalorians, you will find the Navigation Signal in one on the dead Mandalorians remains. Revan then returns to the Mandalorian Swoopbikes, insurtes the Navigation Signal, and the Mandalorian Commander will apear. Revan then kills the Mandalorian Commander with Jolee in his party, gets the Mandalorian helmet from the Mandalorian Commander, and returns it to the Wookiee for a reword.
