AR-312 was the designation for a scan created by the science team at the University of Agamar, which documented a cave located on Bimmiel. Inside the cave, the scan revealed the mummified remains of a humanoid that had apparently been there for approximately half a century (years). The humanoid appeared to have retreated into the cave while defending itself from slashrats. Evidence suggested it had eliminated at least a pair of slashrats before succumbing to its injuries, and weapons along with armor were found close to the body.
After Doctor Pace presented the scan to Corran Horn, Horn was able to identify the humanoid's characteristics as those of a Yuuzhan Vong. These remains would eventually play a role in the confrontation between Horn and Shedao Shai, as well as the devastation that befell Ithor.
