The Tapeno Library resided within the Historical District of Estalle Island, which is found on Procopia in the Tapani sector. Its collection included tens of thousands of books, scrolls, and ordinary holocrons, alongside a comprehensive computer database.
Spanning nearly seven millennia with minimal gaps, the documents held within the Tapeno Library recount the shared history of the Tapani sector. Throughout the passing centuries, the staff have diligently guarded the historical records, resulting in the events depicted remaining largely unaffected by politically driven revisions of Tapani History.
