History
Liam is captain of a ship named the Jewel of the Realm. At one point, he is summoned by their king to sail to Neverland, given a sextant, star charts leading them home and back, and a sail woven from Pegasus feathers. He is instructed to retrieve the plant Dreamshade under the impression it is much-needed medicine for the kingdom. Choosing to bring along his brother, Lieutenant Killian Jones as his right-hand man on the trip, they depart when all preparations are ready.

On the journey there, the Jewel of the Realm is attacked by two other ships from behind. To Killian's awe, Liam orders for the Pegasus feathered sail to be released down and the ship begins to glide in the air into the skies.

Upon their arrival on the island, Peter Pan investigates to see what they are doing. Though at first, they draw their swords in surprise, Liam makes peace by introducing himself and his brother and showing Pan a drawing of the Dreamshade. The boy attests Dreamshade is dangerous and comments that their king must be really ruthless, but Liam pegs his claims as nonsense while Killian chimes in it's medicine. However, Pan presses the plant is doom and exemplifies how easy it could be to kill an entire army with poison instead of a messy onslaught of bloodshed in battle. Liam does not heed the warning, while Killian begins to think the king wants the plant to poison scores of their enemies to death. After finding the plant, Liam, to prove his brother wrong, wounds himself with the Dreamshade. While nothing happens immediately, in the next instant, Liam is knocked out by the rapidly spreading poison. Then, Peter Pan appears to Killian and gives him access to a spring, which will heal his brother, but comes with a price if they choose to leave the island. Killian feeds Liam water from the spring and he awakens completely healed.

They venture off the island with plans of revealing their king's true vicious nature in sending them on the expedition, however, Liam dies suddenly after leaving Neverland's seas. Dying in his brother's arms, his body is later thrown into the sea. His death changes Killian, who takes his place as captain of the ship and renames it the Jolly Roger. Killian reveals to the crew what type of man their king is, to which everyone agrees they need not serve someone so horrible any longer and embrace the life of pirates "with honor" instead.
