Mission to Tython

In around 25 BBY, the Mandalorian warrior (and at the time, treasure hunter) Naastau and his droid R2-T741 traveled to the ancient Jedi homeworld of Tython in search of holocrons and other artifacts. Upon arriving to an abandoned temple, he and his droid were ambushed by dozens of technobeasts, who had aimlessly wandered the temple's halls since the end of the New Sith Wars. The pair managed to destroy a few before fleeing back to the ship and leaving Tython, having failed in their mission to retrieve any artifacts. However, Naastau did manage to bring with him the head of one of the technobeasts that he destroyed, which he turned over to a medical droid upon returning to his homestead on Mandalore. He was shocked to learn that the technobeasts, who he perceived to be no more than ancient security droids, were in fact once living beings who were transformed into mindless cyborgs after the medical droid revealed that the head contained decomposed Human brain matter, and one of the head's sensors still contained bits of a Human eye. Years later, Naastau came across a data entry on technobeasts while searching an abandoned library in the Esstran sector, which confirmed his findings and the history behind it.
