The Skull is a region within the Wushanko Isles found between The Arc and The Hook. It is the second region opened up by the player advancing through the player-owned ports minigame. It is a heavily fortified area in fear of an invasion from the West, possibly due to its proximity. The area is known to have gunpowder, which the Khans use to maintain a warlord status in the area. One-eyed Sea Serpents, Hydras, and Sea Lizards, are found here. After a voyage, the player may have a sailing outpost on Thalassia. The islands of the Skull are:
- Ai Jei, biggest island of the Skull. Produces gunpowder to trade with the rest of the Wushanko Isles, it also produces apples. The ruling khan is territorial and hostile to westerners.
- Echo Bay, home to fishing towns that use explosives in their fishing. The ruling khan is cruel to his people.
- Hanto, island of the Skull ruled by a tyrannical khan who closed the island to trade. According to captains with a specific trait, the khan executes his people publicly.
- The Sunlit Veil, a thin strip of land nestled in shallow, warm seas. Mermaids are known to visit this area.
- Thalassia, where sulphur is mined for gunpowder production. At the centre of the island is a massive jade palace, built by Thalassia's khan.
- Siren's Shell, home of the seasingers; unlocked by a voyage.
- Hyu-Ji, home of the Sea orphans. Ruled by a khan known as Tubjub, and later Marcus Fine.
- Seeker Synapse, a living island that many assume to be an evolved sea monster, but is in actuality a large Seeker from Daemonheim. It has a brain at its centre and other seekers act as its sensory system.
