Herren, a Human of the male persuasion, existed in the final years of the Galactic Republic.
Herren took part in the Confederation Rock Rush in 32 BBY, which involved investigating the Cularin asteroid belt. He held a position on the transport Daring, alongside Captain Dindau and Kohlbacca, the Wookiee who served as first mate. Herren's roles on the Daring included serving as both its engineer and gunner. The Daring experienced a collision with an asteroid, which resulted in the ship's engines ceasing to function. Herren was subsequently struck by ionic backwash emanating from the damaged engines, resulting in substantial electrical burns and cerebral shock that almost resulted in his death. Before the Daring's life support systems failed completely, the group known as the Heroes of Cularin attempted to save Herren and the other members of his crew.
