The Galactic Republic's boom and expansion during the Great Manifest Period had come to an abrupt end in 17,000 BBY with the outbreak of the first Alsakan Conflict. The fighting marked the beginning of the Indecta Era, a period of time in the Republic that saw little Rimward growth and expansion. As the Indecta Era continued, however, the Republic began to make contact with previously unknown sentient species who lived on the Rimward frontier, increasing the diversity of the known galaxy.
In the year 16,782 BBY, as the Indecta Era continued, the library known as the Celebratus Archive was established on the planet Obroa-skai. The archive was a massive collection that featured complete records of over 300,000 species.
The creation of the Celebratus Archive helped to secure the reputation of Obroa-skai as a primary center for research. The massive archive was also remembered in 10,000 BBY by the historian Vicendi, who included the library in his list of the Twenty Wonders of the Galaxy, a part of the text Arturum Galactinum, which was written as an homage to the founding of the Republic.
