Unidentified NPCs are various non-player, interactive characters found through out the Jedi Temple.
Unidentified Jedi 1 Edit
This character is found just a short distance away from Luminara Unduli and the Saber Strike launch. He can be seen using the Force to balance on one hand, and even one finger while levitating three crates around him, but if a player clicks on him, he, and the surrounding boxes, will fall over (a possible reference to Luke Skywalker's fall during his Training in The Empire Strikes Back).
Unidentified Jedi 2 Edit
This character is found on the base floor of the Training Room, and is constantly practicing cutting holes in bulkheads and walls, along with two other characters.
