In the Mandalorians' native language of Mando'a, Canderous roughly translates to "important rock." Canderous Ordo lived up to his name many times over throughout his illustrious career as a Mandalorian warrior. Not only was he an important figure in the Mandalorian culture, but he was also a steadfast rock to anyone lucky enough to gain his loyalty. He left many adversaries dead in his wake and left a legacy that remained in the minds of Mandalorians for hundreds of years to come, possibly even to the time period in Star Wars: The Old Republic.
At the early age of eight, Canderous began his training as a Mandalorian warrior. By the time he reached his thirteenth birthday, he passed the traditional rite of passage known as verd'goten and became an adult member of the Mandalorian clan Ordo. His skill at controlling the Basilisk war droid was unmatched amongst his ranks, and he quickly became one of the fiercest and most accomplished warriors to wear Mandalorian armor. Eventually, the name Canderous Ordo fell upon the ears of Mandalore the Ultimate, the new Mandalorian leader who was beginning to reassemble the recently defeated Mandalorian Crusaders under the new banner of the Neo-Crusaders. Recruiting Canderous to their ranks was an easy decision.
Canderous' role in the coming wars changed from what he was formerly accustomed to. Under Mandalore's command, the young warrior became an expert of battle tactics, eventually earning the rank of Commander. His ascension through the ranks brought him honor amongst most of his Mandalorian brothers, but some thought he threw away lives in order to further his own glory. Regardless of what the other soldiers thought of him, Canderous's ability to lead his men into battle and return triumphant continued as Mandalore pushed into Republic space and began the Mandalorian Wars.
Canderous took the title of Mandalore the Preserver and vowed to rebuild the Mandalorians to their previous strength in order to guard the Republic against the threat that Revan feared. He gathered the Mandalorians on the Dxun moon in the Onderon system where he continued to recruit beings to his cause. Five years later, fate brought another member of his past into his life once again. One of Revan's former Jedi Generals from the Mandalorian Wars arrived on Dxun aboard the Ebon Hawk with her crew in search of one of the survivors of Darth Nihilus's Jedi Purge.
The presence of the Ebon Hawk and Revan's old utility droid, T3-M4, piqued Canderous's curiosity. He agreed to help the Jedi, who had been exiled for disobeying the Council's orders during the war. During their adventures together, it became obvious to Canderous that the Sith presence was a dangerous one. He called his Mandalorians together and led them in the Battle of Telos IV against the Sith fleet and its leader, Darth Nihilus. During the battle, Mandalore joined with the Jedi Exile aboard the Sith flagship Ravager and defeated the Dark Lord.
Canderous and the Jedi Exile parted ways to continue their separate journeys. The exile went in search of Revan, and Canderous--as Mandalore the Preserver--returned to the task of rebuilding the Mandalorians. However, it is unclear how successful he was in this endeavor. Fourteen years before the Treaty of Coruscant, the title of Mandalore was up for grabs. The Sith Empire secretly rigged gladiatorial battles to favor that of a man calling himself the new Mandalore. Once he obtained the official title of Mandalore, he rallied Mandalorian mercenaries together and launched an offensive against the Jedi Order. This is not what Canderous had in mind when he followed through with Revan's last wish.
Not all Mandalorians agreed with the Empire's psuedo Mandalore. After a bitter defeat in the Hydian Way trade route shortly after Mandalore took power, a group of Mandalorians formed that remembered the edict of Mandalore the Preserver. They felt that they should support the Republic, instead of the Sith Empire that had placed an unworthy puppet at the head of the Mandalorian clans. Unfortunately, the rebellion did not last long. The winner of Mandalore's own Great Hunt bested him in a duel and took the name of Mandalore the Vindicated. He then used his influence to amass an army that put a stop to the followers of Mandalore the Preserver's legacy. One has to wonder if Canderous of clan Ordo would be disappointed that his successors failed, or if he would be honored that they fell to a great warrior worthy to lead the Mandalorians into battle once again.
