Rakatan guardian droid

The Rakatan guardian droids of Lehon were built by the Rakata during the height of the Infinite Empire.

One such droid was used as an overseer for the construction of the Star Map temple on Dantooine. It was left active in case a Rakata should return to inquire about the Star Forge. As of 3956 BBY, no Rakata had entered the area for twenty-five millennia. However, the droid was still functioning and able to serve the first person that entered, Revan, a testament to the quality of its construction. This droid was nearly 25,000 years of age, older than the Galactic Republic itself.

As overseers of slaves, these droids were programmed with the languages of the Rakata slave species, including Selkath, Tusken, and Rakata. When activated, they would repeatedly speak a phrase, cycling through the languages they knew until the individual interacting with them responded in the same language. For example, when Revan and Bastila Shan entered the Dantooine temple, the Overseer droid attempted interacting with them several times, until they both recognized it's ancient form of Selkath, After this it communicated with them in that language.

They had significant armor as well as a powerful array of weaponry, and if deactivated, could be fully repaired and reactivated through a computer terminal. During the Battle of Rakata Prime, Darth Malak activated a number of construction units to continuously spawn these droids in order to halt, and hopefully kill, his former master, Revan.
