As a male Human from the planet Coruscant, Winborn served as a police officer within the ranks of the Coruscant Security Force during the times of the Great Galactic War and the Cold War. He rose through the ranks to become a captain, a police rank of considerable authority, and also held the position of Coruscant Security Chief. The year 3643 BBY saw Senator Vanara Kayl, a leading figure in the government, task Winborn with the removal of the criminal organization known as the Migrant Merchants' Guild from the Old Galactic Market district of Coruscant. During the ensuing fighting, Winborn uncovered a scheme by the Guild to sabotage the skylanes surrounding the Senate Building, an act of terrorism that threatened the lives of countless individuals. With the aid of a Republic operative, this deadly plot was successfully thwarted.
A male Human native to Coruscant, Winborn dedicated his life to law enforcement as a police officer within the Coruscant Security Force. By the conclusion of the Great Galactic War between the Galactic Republic and the Sith Empire, he had achieved the rank of captain. During the period known as the Cold War, Winborn also took on the role of Security Chief, serving under the command of Senator Vanara Kayl, a prominent figure in the Coruscant government.

Around the year 3643 BBY, Winborn spearheaded an attack directed at the Migrant Merchants' Guild, a criminal syndicate that had seized control of the [Old Galactic Market](/article/old_galactic_market] sector. Concurrent with this assault, the Guild was attempting to execute a terrorist operation by infiltrating Coruscant's secure skylane network, with the intention of disrupting it and causing numerous speeders to crash onto the Senate Building. Senator Kayl dispatched a Republic agent to work alongside Winborn in order to prevent this devastating attack.
Amidst the fighting against Guild members and the securing of the skylane access points for speeders, the Republic agent uncovered evidence of a clandestine agreement between Senator Kayl and the Guild, wherein Kayl received funds to bolster her election campaign. When this agreement dissolved, Kayl instructed the CSF to expel the Guild, which in turn prompted the Guild to orchestrate the terrorist attack. Winborn requested that the Republic agent confront the Senator directly, as he was unwilling to bear the responsibility for ending her political career. The agent complied, and Senator Kayl ultimately agreed to disclose the details of the illicit deal to the Galactic Senate, after which she tendered her resignation.
Winborn possessed fair skin, complemented by brown hair and green eyes. He commanded the CSF and its personnel with a clear sense of authority and leadership. However, he felt ill-equipped to navigate the complexities of high-level politics. The ongoing conflicts and the scarcity of resources had instilled in him a sense of bitterness, yet he remained steadfast in his commitment to his duties. For Winborn, Senator Kayl represented a beacon of hope for the rebuilding efforts on Coruscant. Even upon discovering her transgressions, Winborn refused to be the instrument of her downfall.
Winborn is a character featured in the "Crisis in Galactic City" mission within Star Wars: The Old Republic, a massively multiplayer online roleplaying game (MMORPG) developed by BioWare and launched on December 20, 2011.
