Tyloor, a Kedorzhan, was one of Senator Dewell Bronk's seven children. His father was a representative of the Galactic Republic. In the Clone Wars, a war fought between the Republic and the Confederacy of Independent Systems from 22 BBY to 19 BBY, Tyloor gave his life in service to the Republic. His remains were never recovered following his demise on the battlefield. Dewell's decision to endorse the Petition of 2000, which denounced the wartime conduct of Supreme Chancellor Palpatine, was partly influenced by the death of his son.
The short story "Incognito," penned by John Jackson Miller, included a reference to Tyloor Bronk. This story appeared in the 143rd issue of Star Wars Insider magazine, which was released on July 23, 2013.
