Ecologically, the world was a terrestrial mix of tundras, mountains, grasslands and deserts. A standard day was 26 standard hours and a standard year 456 local days.
The reputation that had developed over the centuries was that the complete knowledge of the galaxy had been gathered within the computers of Obroa-skai's information repositories. Obroa-skai was also home to a large collection of Jedi-related antiquities which were destroyed by the Imperial Security Bureau.
Obroa-skai was captured by the Yuuzhan Vong during their invasion of the Galaxy, and a yammosk was installed in the planet's mantle. Much was lost from the archives, but hardcopies of key items were saved before the assault. The Yuuzhan Vong kept many of the copies intact, at least until they could get them fully translated. As such, much of the planet's buildings were kept intact despite heavy Vongforming on other areas of the world. Obroa-skai was later liberated from the Vong, and the yammosk was destroyed.
In 43 ABY, Obroa-skai was recovering from the Yuuzhan Vong War and the resultant terraforming on its surface. Institutions such as the Aurora Medical Facility were in operation as of this time.
