In 3958 BBY, Admiral Saul Karath defected from the Galactic Republic to Revan's Sith Empire. Karath had served as a respected Republic officer during the Mandalorian Wars and had been a mentor to Carth Onasi. His defection gave the Sith both an experienced commander and intimate knowledge of Republic military systems.

SAUL KARATH'S DEFECTION
Documented history and chronological boundaries
Admiral Saul Karath, previously a Republic officer and mentor to Carth Onasi, transferred his allegiance to Revan's Sith Empire in 3958 BBY. His experience in the Mandalorian Wars had provided familiarity with military procedures, ships and personnel. The defection mattered strategically because Karath could apply his professional knowledge against the institution that trained him. It also mattered personally to Carth, whose relationship with the admiral had once rested on confidence and respect.
People, political institutions and material life
Defection is an institutional transfer of specialized knowledge, not simply a change in uniform. Expertise about defensive procedures and other officers can magnify the effect of a political realignment. Carth's later grief and mistrust show how loyalty to an institution and loyalty to a former mentor can come apart. The sources do not establish that Karath's betrayal made every former Republic subordinate a Sith sympathizer.

Expertise crosses the line with the defector
Karath carried more than his own labor to the Sith.
He brought knowledge of Republic procedures, communications, defenses, and officer culture.
Betrayal is experienced through relationships
For Carth Onasi, Karath's defection was not an abstract change of allegiance.
A former mentor's choice transformed institutional distrust into personal trauma.
Anthropological assessment
Defection demonstrates that institutions depend on knowledge held inside people, not only on buildings and formal rules.
When an experienced insider changes sides, social relationships and procedural knowledge can become weapons.
The Old Republic / connected history
A Republic admiral changes the side he serves
Saul Karath's defection gave Revan's growing Sith regime an experienced Republic naval officer with knowledge of the fleet, command procedures and the habits of his former colleagues. The action belongs to the early Jedi Civil War, when the old lines between Republic and Sith military personnel were shifting. An officer's defection differs from a ship being captured in combat because it transfers institutional knowledge as well as equipment. Officers know communications routines, logistics and the political relationships through which a navy operates.
Karath later commanded Sith naval operations, including the bombardment of Taris, and became one of the recognizable agents of Malak's state. His career shows why the enemy's strength cannot be attributed only to the Star Forge or the power of Sith Lords. Defectors and administrators can make a new regime effective by carrying skills developed in a different political order. Those skills remain useful even when the officer's allegiances change dramatically.
Military institutions transfer through people
A fleet is not made from hulls and weapons alone. It requires navigation, crews, training, schedules, command conventions and trust among officers. When an admiral defects, he can reorganize that knowledge for a new ruler. The move also affects the morale of personnel who once relied on the officer's Republic oath.
How later violence changes a biography
It would be misleading to describe Karath only through the moment of transfer. His subsequent acts toward civilian worlds reveal the consequences of serving Malak. At the same time, later wrongdoing cannot be projected backward as exact proof of every motive Karath held before defecting.
Did the Star Forge by itself explain Karath's usefulness to the Sith?
No. He brought Republic naval experience and command knowledge. Ship production and experienced leadership were different components of Sith military power.
