Lobot-Tech headgear was an Imperial technology designed to increase productivity in low-level workers. The cybernetic implant, however, would often erase the personality of its subject and, occasionally, cause their behavior to become erratic. Lando Calrissian's aide utilized the technology, as did a Rodian named Tseebo, who used the Lobot-Tech headgear to steal Imperial data and plans.
Growing up on his own during the age of the Empire, Ezra Bridger relied on his street smarts -- and subconscious Force abilities -- to survive. He became a con artist and small-time thief, doing what he needed to get by on his home planet Lothal. But this reality also hardened Ezra, who by the time he was 14 years old, had little trust for anyone. That would change with his introduction to the Ghost crew, a small band of rebels fighting back against the Empire. Ezra came to believe in their cause, and saw that he could help change the galaxy for the better. And with the help of Kanan Jarrus, he began to learn the ways of the Jedi.
Lothal is a diverse planet, with both farmland and a city center. During the age of the Empire, it fell under Imperial occupation, as farmers were kicked off their land and enormous TIE fighter and weapons factories were built. While most of the population felt powerless in the face of Imperial rule, a select few dared to fight back.
