Woolif was a medical professional of the Ruurian race who practiced medicine throughout the time of the Republic Era. His medical training occurred on Alderaan while he was in his larval stage, and he subsequently practiced on Zygerria, Mon Cala, and Lothal. To ensure the preservation of his memories and knowledge following his transformation into a chroma-wing, Woolif underwent cyborg enhancements before this final stage of his species' lifecycle. Following his metamorphosis into a chroma-wing, he continued his service on numerous other planets, ultimately finding himself working in New Xaxxis, a city located on the planet of Metagos. It was during Mace Windu's mission to Metagos that he encountered the Jedi Master, offering assistance to the Jedi in his objectives.
