The Free Dac Volunteers Engineering Corps, alternatively referred to as the Quarren Free Dac Volunteers Engineering Corps or QFD, functioned as a builder of starships throughout the Clone Wars period. Their most prominent creation was the Providence-class Dreadnought. The QFD's workforce was mainly made up of Quarrens, a species originating from the world of Dac, who had pledged allegiance to the Confederacy of Independent Systems. They maintained a collaborative relationship with Pammant Docks, and operated manufacturing plants situated on the planet bearing the identical designation.
Tikkes, a Quarren official, acted as the QFD's representative within the Confederacy. In the aftermath of the Clone Wars, specifically five years later, a transformed military vessel assaulted Sentinel Base, an isolated Imperial installation. Analysis of the ship indicated that certain elements originated from the Invincible and the Lucid Voice, Providence-class cruiser-carriers produced by the Free Dac Volunteers Engineering Corps. Consequently, the Empire initiated an inquiry to determine if either QFD or Pammant Docks played a role in the construction of the warship.
