The Ironclads are included in the Procyon fleet list, which gives away the twist ending somewhat. In the game, there are three separate factions: the Royal Navy, the Procyons and the Pirates. However, Jim believes that Silver survived and is out there somewhere gathering a new fleet. Silver is presumed dead, and receives a posthumous pardon and knighthood. The Procyons are forced into harsh peace terms thanks to their treachery, and the Empire is saved. He rams Evar's flagship, and both ships are destroyed. An enraged Evar attempts to take Jim down with him by ramming his ship, but Silver's badly damaged ship arrives. A massive battle ensues, ultimately resulting in the Procyons' defeat. They arrive at Parliament, only to find the Procyons have already sprung their trap. Silver regains command of his fleet, and, together with Jim's fleet, rush back to Parliament to stop the Procyons. Jim learns that Silver was captured by a robot doppelgГ¤nger, who has been aiding the Procyons in his name. Jim pursues Silver to a pirate fortress, where he discovers two identical command ships, both commanded by a Silver. However, they are soon intercepted by Silver's pirate fleet. Jim is ordered to warn the Empire of the Procyon trap. After locating and destroying an Ironclad base hidden in a nebula, he discovers the Ironclads are Procyon vessels, meant to draw the Navy fleets to the Frontier, allowing the 'Diplomatic' Fleet to kidnap the Queen unhindered.

After missing out on a chance to join the fleet scouring the Frontier for Ironclads, Jim is sent to investigate Ironclad activity after finding one apparently lost deep in Empire territory. However, bizarre and almost unstoppable iron ships nicknamed Ironclads wreak havoc in Imperial territory, and pirate raids are a constant.Дuring his patrols, Jim discovers his old friend Long John Silver's flagship is in command of the pirates aiding the Ironclads. They send a diplomatic fleet under the command of Procyon diplomat Evar to Parliament, the centre of government and home of the Queen, for the peace talks.

As Jim patrols various sectors of the Etherium, Her Majesty's Empire is in the process of negotiating peace with the Procyons, raccoon-like warriors who have been at war with the Empire for centuries. Five years after the events of Treasure Planet, Jim Hawkins graduates from the Royal Navy Academy and becomes commander of an Imperial patrol ship.
