A blank Jawa droid builder certificate signed by Wimateeka
The tiny Jawas residing on Tatooine presented a Jawa droid builder certificate to individuals who achieved the status of Master droid builder. This honor was bestowed after completing training within their massive sandcrawlers. Notably, during the era of the Galactic Civil War, a Rebel Alliance agent received such a certificate. This was earned by effectively reprogramming a new series of Imperial assassin droids. The certificate given to this agent bore the signature of Wimateeka, who was the Jawa chieftain of the Nkik clan.
Despite being attributed to Wimateeka, the signature visible on the certificate given to the player in the game Star Wars: DroidWorks actually spells out "Wimattea" when written in Aurebesh.
