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.

The Occultist has earned his affections, much to the chagrin of his wife, and the Portmaster often uses their friend to influence him.
- The Khan of Echo Bay is disliked by the Portmaster for being cruel to his people. The Portmaster regularly sends raids against his mercenaries and merchants alike.
- The Khan of Ai Jei's wife, is an ally made during A Friend Indeed. She has a great distaste for her husband.
- A Mermaid at The Sunlit Veil, befriended during A Friend Indeed. She is a useful informant on the area.
