The Siege of Morjanssik was the second major strike conducted by the Quarren Survivalist Party during the Dacan Civil War of 16 ABY. It was also the first operation conducted after their existence was revealed to the Mon Calamari Council. The siege began in the farium mines lining the ocean trench below. Operating with fresh weaponry and armed submersibles, they were able to gain control of the mines quickly. Then, waves of Quarren soldiers assaulted Morjanssik's perimeter.
