The hideout of Deathwatch served as a base of operations for the Mandalorian terrorist organization known as Death Watch. This base was situated on Mandalore's moon, Concordia, during the era of the Clone Wars. Originally, Mandalorian miners constructed the hideout, but Death Watch utilized it as their base until Jedi Master Obi-Wan Kenobi and Duchess Satine Kryze uncovered its location in 21 BBY. Upon their discovery of the Mandalorian warrior group, a conflict ensued, culminating in a duel between Kenobi and Pre Vizsla, the former governor of Concordia who secretly commanded Death Watch.
