The Kingdom Stone is the crystalline concentration of the energy supplies of the starship that brought the Ancient Dragons to Avalice. According to the Royal Magister, the Three Kingdoms of Avalice (Shang Tu, Shang Mu & Shuigang) have depended on the Kingdom Stone for centuries, using it's energy to power their technology.Before it's destruction in Freedom Planet, the Kingdom Stone resembled a sparkling crystal orb . It had the colours of Opal (Purple) and Sapphire (Light Blue). After it's destruction, it becomes a crystalline vortex of the same colors. It is likely the vortex transformed into a planetary ring as seen in the Sample Version of Freedom Planet 2.
By the time of Lord Brevon and his army crashlanded on Avalice, the Kingdom Stone's power was supposedly fading, unable to keep up with the energy demands. Prompting to a seeming energy crisis, Mayor Zao of Shang Mu hired Spade and the Red Scarves to help his Soldiers in steal it from the Ancient Temple, in order to preserve his Kingdom's power and to also increase his chances for re-election. Around that time, Brevon had just murdered the King of Shuigang and brainwashed his son, Prince Dail, to steal the Kingdom Stone to recharge his Dreadnought so he could continue his galactic conquest, leaving the Three Kingdoms of Avalice on the approach of civil war.After Lilac convinces the armies of Shang Tu and Shang Mu to unite against Brevon with the Holodragon, a large assault on the Dreadnought's refueling station takes place, but not before the warship makes liftoff with only Lilac, Carol, Milla and Torque getting on. When Lilac and Carol almost succeed in disconnecting the Kingdom Stone from the ship's engines, Brevon forces them to stop their attempt when he turns Milla into a mutant monster and has her attack them. Milla is defeated and presumed dead, but this act only enrages Lilac and Carol, who break through the last of Brevon's defenses and make their way to another area of the Dreadnought, where they confront overlord himself and the final battle takes place. As the dreadnought exploded, the Kingdom Stone was destroyed, only for its energy to reincarnate as a crystalline vortex that hovers over Avalice. The Royal Magister of Shang Tu explains and realizes that the Stone was the reason for emitting limited energy to begin with.
Freedom Planet 2 Edit
With the destruction of the Kingdom Stone, the crystal prison holding Merga has been destroyed. It would seem that during the Avalician War, the Kingdom Stone's power may have been used to imprison Merga when she grew ruthless and power-hungry. Now that she's free, Merga sets out to unleash the ancient super-weapon Bakunawa on the Three Kingdoms as an act of vengeance.
