Garek Tolas was a Human male who initially served the Alliance to Restore the Republic, and subsequently the New Republic.
Tolas's career began within the ranks of the Galactic Empire, specifically as a member of the Imperial Special Forces. His allegiances shifted, however, when he was assigned missions requiring the killing of civilians. This led him to defect and join the Alliance to Restore the Republic, where he became part of the crew aboard the YT-1300 light freighter named Lazy Katarn. During 3 ABY, Tolas and his fellow crewmates on the Katarn were dispatched to the planet Dalicron-4 with the mission of locating Caeleb, known as the "Child of Light." Tolas played a role in the defeat of the Dark Jedi named Tol Skaros, who had attempted to capture both Caeleb and the Rebel forces.
Following this, four months later, Thaum Rystra kidnapped Caeleb, prompting the crew of the Katarn to once again embark on a mission to find the child. Their pursuit led them to Nar Shaddaa and then to the planet Pamorjal. The Pamorjal Freeman's League destroyed the Lazy Katarn, forcing Tolas and the other Rebels to switch to piloting the YT-2000 light freighter called Celestial Dancer. Ultimately, they confronted and attacked Rystra within the Cavern of Light, successfully rescuing Caeleb.
Later in his life, Tolas married Mina Dhori, and when the Alliance transformed into the New Republic, he continued his service under the new government. In 7 ABY, Tolas and the crew of the Dancer journeyed to the Temple of Pain located in the Tascollan Nebula, where they faced off against both Rystra and the spirit of the Sith consort Valik Kodank.
