The Celebratus Archive, situated on the planet Obroa-skai, was a library containing comprehensive documentation from more than 300,000 distinct species. The library's establishment in 16,782 BBY cemented the world's standing as a center for scholarly investigation. Vicendi, the historian, listed the archive as one of the Twenty Wonders of the Galaxy within his Arturum Galactinum published in 10,000 BBY. Forces commanded by Grand Admiral Thrawn raided the library with the goal of discovering the whereabouts of the world Wayland.
