Gommu Erfo

Gommu Erfo was a male Prollian that was one of the owners of the droid and mining factories on Prolla. He was also the one who signed the treaty with the CIS prior to the Clone Wars as a representative of his world.

Secession of Prolla
In 31 BBY he was sent to a secret meeting with a droid ZID-17, that brought special orders from a dark jedi Trillak. The Prolla Administration was to declae its planet independent, and in case of a denial was to invade Anarmar.

For this ZID-17 asked the Prollians to convert their mining droids into battle droids and start the invasion with the aid of Prolla mercenaries. The city was occupied within several days.

Unfortunately the Prolla droids were very primitive to carry out such a mission, and ZID-17 was controliing them untill he received a new assignment from his master - locate and capture the Prime Minister of Anarmar. While the droid was away the Prollians lost control of the city, and were eventually defeated in a battle against the local security forces.

Still Prolla became independent as Erfo and his colleagues desired.

Clone Wars
It was 23 BBY when ZID-17 contacted Gommu Erfo to make a new version of Prolla battle droids and send them to Elecria to aid the local separatists attack the governmental buildings. In 21 BBY the Elecrian revolutionaries managed to take control of the planet and signed the treaty with the CIS together with Prolla.

On Elecria he met Gedar Olmo, who was the commander of CIS forces on Elecria, and was now receiving orders from him. Sometimes Gommu would say to his friends that he didn't trust humans, and especially this Olmo. But he feared the dark jedi, and remained silent most of the time.

When the Republic troops arrived in Elecria city, he fled the city together with other separatists.

Eventually he was killed at the very end of the Clone Wars.

Behind the scenes

 * Gommu Erfo was not the only Prollian present on Elecria during the Battle for Elecria, there were others, that were not so lucky to escape the city, and were captured or killed.
 * Gommu Erfo reminds the PK-series worker droid from The Phantom Menace.
