Sirrus, a Human male, was a Jedi Master within the Jedi Order. During the Clone Wars, he served the Galactic Republic as a General in the Grand Army of the Republic. Furthermore, he mentored Aubrie Wyn as her Padawan.
A Force-sensitive Human, Sirrus received education in the Force from the Jedi Order, ultimately achieving the rank of Jedi Master. He chose Aubrie Wyn, an Initiate, to be his Padawan, and he fostered her talent for Force healing until she was selected for specialized instruction with Master Mace Windu.
Before Sirrus could fully develop Wyn's abilities, they were both compelled to participate actively in the Clone Wars. Taking on the role of General within the Grand Army of the Republic, Master Sirrus and his Padawan were deployed to Jabiim to engage in the campaign there. Serving under the command of Jedi Obi-Wan Kenobi, Sirrus fought alongside Kenobi, but he perished when Separatist forces destroyed a Republic walker.
Sirrus also carried a holocron, for reasons that remain unclear. During the Battle of Jabiim, he entrusted this holocron to his Padawan, who subsequently passed it on to Anakin Skywalker, so that Skywalker could return it to Coruscant.
