Obrai-Skai

"Obrai-skai" system is located in the Borderland Regions of the galaxy. The system occupies a strategic position between those portions of space controlled by the remnants of the Empire and the New Republic.

The system is renowned for its massive library, located on the primary planet (also named Obroa-skai).

The reputation that has developed over the centuries is that the complete knowledge of the galaxy has been gathered within the computer of Obroa-skai's information repositories.

It was from these library computers that Grand Admiral Thrawn pulled the astrogation coordinates of the planet, Wayland.
