House Hirskaala was a trading concern operating from Cularin. It was founded in the wake of the Trade Federation being pushed out of the Cularin system in the Trade Wars. They had offices in Gadrin near the center of the town.
In 31 BBY, an employee of House Hirskaala named Darin was kidnapped by pirates dressed in stolen Hirskaala security uniforms. Within a month of that incident, several Hirskaala security employees disappeared themselves to join the Cularin resistance, including Hirskaala's head of security, Nim'Ri. Yaeger Doru became head of security during Nim'Ri's absence.
