I was spelunking caves last night and ventured into one of his dens with the man's Desert Armor, and literally followed the directions he put in his terminal; "Going to cave south" and tracked his caves down until eventually I was left at a cliff-hanger with his dialogue "Princible better not show" or something akin to that. Are there more terminals? I need to know! Anyone have any idea on this? Please let me know if anyone finds anything about this.
