These are the primary docks in the central hub of Acionna's Sorrow. There are four dorsal-side and four ventral-side docks capable of receiving ships up to five hundred meters in length, however, two of the dorsal-side docks have been destroyed due to the destruction of Kayurata warships. One of the ventral side docks is permanently flooded while another cannot receive large submarines due to severely damaged moorings.
There are a dozen of other docks capable of receiving small boats and strike crafts on the dorsal and ventral sides.
