- "Why of all worlds is he on Vallt? You realize Vallt has gone over to the Separatists?"
"I do. But Vallt was a Republic member world when Dr. Erso agreed to oversee Zerpen's onworld facility. A deal was cut with Vallt's former leadership that allowed for mining and construction in return for a very generous aid package."
- ―Mas Amedda and Orson Krennic
Vallt was a planet located in the Outer Rim Territories that was the homeworld of the Valltii and Taqwa species, and also the birthplace of Jyn Erso. Vallt was a cold world, with half the planet covered in glacial ice. The climate was often snowy and windy and quite inhospitable to off-worlders.
Galen Erso and his team were working on Vallt for Zerpen Industries when the Vallt government was overthrown in a coup by those sympathetic to the Separatist movement. This led to Erso quickly being thrown into Tambolor prison on charges of espionage. The planet thus shifted from being a Republic–aligned planet to a Separatist one during this period.
- "I can only wonder what Count Dooku offered Vallt's new leadership. Perhaps he promised to tug this world a bit closer to your star."
"Trade, respect, fair representation in the Confederacy. All that we weren't receiving as a member of the Republic."
- ―Galen Erso and Chieftain Gruppe, after Phara's coup
The Outer Rim snow planet Vallt had been a member world of the Galactic Republic for years before the Clone Wars. Whilst it was a member, it did not receive much trade or respect from the government, and also lacked fair representation in the Republic. For around a decade, Vallt's representatives brought this to the attention to the Republic, but this did not change their status. During his time as Chair of the Senate, Mas Amedda served on a committee with Vallt representatives, but did not grant them the support they wished.
