Anno Wen-Chii was a reclusive Pyn'gani Jedi Master who lived near the end of the New Sith Wars. In 995 BBY, he and his Padawan, Nalia Adollu, went to his homeworld, Polus, to study life-forms; they were not seen on Coruscant for the next five years. Wen-Chii was a good friend of the Jedi librarian Barra-Rona-Ban, with whom they had studied together.
