Since it's not been mentioned yet, Azys Lla was a military R & D Facility that specialized in chimerical, Draconic, and void sent bio-reserch.

Many of the parts of Azys Lla actually weren't open to the public due to the amount of danger involved with the research.

Based on some of the nodes dialog, it was also used as a military training ground up until the implementation of the Military Machines taking over as the sole military force.

Any scientists and personnel that didn't escape were likly killed and/or devoured by either the Myricidian Dragons or The Chimeric Beasts.
