- "You will have gone from being the Sith Lord himself, to the savior of our galaxy."

Revan was a Jedi Knight and General during the Mandalorian Wars. A Human male once known by the nickname, the Revanchist, he was both a charismatic and enigmatic leader, a renowned tactician and expert strategist, and a hero of the Galactic Republic during the Mandalorian Wars, leading the Republic fleets to victory after victory. Ending the conflict personally, with the execution of Mandalore the Ultimate and the destruction of Malachor V; Revan led the remains of the Republic fleet deep into the Unknown Regions to hunt down the remaining Mandalorians. He returned however, as Darth Revan, the Dark Lord of the Sith.
Deploying his vast armada, the very ships that had fought alongside him during the Mandalorian Wars, against the Republic fleet; Revan ignited the Jedi Civil War. Once again, Revan and his Sith apprentice Darth Malak claimed repeated victories against the Republic, and in the process established a powerful new Sith Empire. For two and a half years Revan's fleet cut a swathe through the Republic fleet before the Dark Lord was finally betrayed by Darth Malak, and captured by the Jedi Order.
Thought dead to the entire galaxy, thanks to the intervention of Bastila Shan, Revan's mind was severely damaged although alive. Unable to restore the Dark Lord's memories, the Jedi Council repaired what they could of the damaged mind, programming a new identity into Revan: one loyal to the Republic. In the year that followed, Revan and a company of followers scoured the galaxy for the source of Malak's strength of numbers. Despite eventually learning of his previous identity, Revan rejected the evil of his past, defeated Malak and ended the very war he had begun.
A year later, Revan once again departed for the Unknown Regions. A former Jedi master of Revan's, the aged Kreia, believed that Darth Revan's brutally efficient invasion of the galaxy had been part of a complex plan to secure the Republic from a long-hidden threat known as the "True Sith", and suggested that Revan had departed on a solitary quest to defeat them once and for all.
- "Some said that Revan was born in the Outer Regions, beyond the Rim, and that's what called to him during the Mandalorian Wars… and after. It was the call of home."
The exact details of Revan's early life cannot be ascertained. Though there were those that claimed he had been born beyond the Outer Rim Territories, his parentage, homeworld and birth name remain unknown. Regardless, he was eventually deemed suitable for instruction in the ways of the Force by the Jedi Order
- "Revan had many masters, Zhar, Dorak, Master Kae before Kae left for the Wars. Towards the end of his training, he sought out many to learn techniques. It is said that he returned to his first master at the end of his training, in order to learn how he might best leave the order."
In the non-canonical ending Revan kills Malak and declares himself Dark Lord of the Sith.
