Emppu Praji-Barck was a woman belonging to the Praji family. Her lifespan occurred sometime in the period spanning from 4800 BBY to 4225 BBY.
For a period of sixty years, Praji-Barck held the position of State Minister within the Galactic Republic. Throughout her tenure, she persistently obstructed any initiatives aimed at involving the Republic in the Kaikielius system, with the intention of suppressing piracy in that region. Because Kaikielius was the base of operations for House Vahali, a family that rivaled the Praji family, Praji-Barck observed as the troubles on the planet drained the Vahali family's financial resources. Ultimately, in 4225 BBY, the Republic dispatched troops to Kaikielius, and Derrica Praji, her great nephew, went along with them, even though he was concerned that his actions might provoke his aunt's anger. Praji-Barck secretly influenced the Odominic kajidic to provide resources to both factions engaged in the conflict, but Derrica came across some data tapes that revealed her involvement.
