The natural terrain of Planet 12 is generally volcanic, with very few plants. The ionized gas in the planet's magnetosphere comes from volcanic activity in its satellites. The diameter of the magnetosphere is one eighth of Earth. An entire half of the planet is covered with many mechanical facilities, where most of the aliens live. Notable locations include Makka, the International capitol, and the Imperial Palace for which Lily Clark lived.
Early history (1500 BC-1908)Edit
Originally, Planet 12 was home to the Terbs, the early relatives of the Tsurbs. Eventually, in around 1,500 B.C., Makkans settled on the planet, building unusual-looking structures that could be used in everyday life in order to make their presence known.
From 1909 to 1946, the Emperor ruled Planet 12 from inside his palace. Noted for his cruel and tyrannical nature, he made life extremely difficult for the aliens, meting out harsh punishments for the smallest misdeeds. Men who dared to stand up to him were never seen again. When a Makkan named Bemb did not bow low enough, the Emperor made him a servant at his Palace, though the latter soon became a guard. Many aliens died out, and the inhabitants believed everything they loved would be destroyed.
Reign of Lily ClarkEdit
In 1946, a twelve-year-old girl named Lily Clark accidentally teleported to Planet 12, where she encountered an Makkan guard named Bemb. The guard finally warmed up to her, and found himself willing to tell her how tyrannical the Emperor of their planet was. Using her charm, Lily was able to convince him to take her to the Palace. Aware of what the planet had to endure, she tricked Rodena into shooting down the Emperor. The aliens were ecstatic at the end of their oppression, and honored Clark as the hero of Planet 12. Lily was then appointed as their holdout ruler by Charlien. After taking the throne, Lily chose to keep the teleportation device in tow.
As one of her first acts as Empress, Lily Clark appointed Bemb as the Captain of the Guard. Clark, who spent most of her time secluded in her Palace, also made it a priority to learn the dialect of her people.  Finally, Lily returned the teleportation device to Earth through Makkalian. In the 1960s, Mr. Demonic NoHead traveled to Planet 12, hoping to convince Lily to associate herself with the NoHeads. Clark, who saw the NoHeads as nothing more than a childish rebellion, refused to help him. Some time afterwards, Lily entered into a partnership with the weapons dealer Tyber Iavanna. However, Iavanna moved to kill her in the end, and Clark suffered a rare defeat when Mesakk switched sides for triple pay and Iavanna and Uraia Nen were able to destroy the Robota Mark II. Tyber killed Lily’s men and forced the administrator to agree to a ceasefire that called off the bounty on his head.
Lily continued as the successful ruler of Planet 12. Eventually, she began training Charlien, the Prince of Planet 12, personally and instructed him in the ways of martial arts. Finally, she hired Tabahelma in her place and resumed position on her throne. Lily continued ruling Planet 12 until she became sick in 2046. Before she died, Lily requested that Charlien be crowned the next King.
Reign of CharlienEdit
Second NoHead WarEdit
In 2019, a female administrator sent an alien warrior to invade Earth, for which she and the other members of the Grand Council would then join him. He was required to give the signal for their arrival. When he arrived, Peter Hecks climbed into the spaceship he had come there in and finally took over, blowing up the UFO in quick order. The alien's death ultimately prompted leading authorities on Planet 12 not to risk such an aggressive move a second time. In addition, Peter Hecks' extraordinary talent was discovered as a result of the fight, setting the stones to end three different wars and purge any factions in four other countries.
The Imperial Palace was originally the Palace of the Republic. During the Dark Empire, it became the Emperor's official residence and was drastically expanded, becoming the largest building on Planet 12. When Lily Clark became the Chief of the planet, she lived in the Palace.
