Energy Nede is a planet rich in culture and technology. I can't see how much more advanced it can get.
Energy Nede is an overdeveloped planet whose government ruled the universe 3.7 billion years ago with science and economy, living in a utopia. It is located in the Theta Sector, near the Arcura System, which it crosses every 7000 years. Its capital is Centropolis, also called Central City, and ins inhabitants are called Nedians. It makes its appearance in Star Ocean: The Second Story and its remake, Second Evolution.
About four billion years ago, Nede ruled over forty civilized planets. One day, however, these civilizations became tired of their rule and started a secret rebellion against Nede, and awaited for the right time to strike. At that time, Dr. Lantis was working on a project: he created the Ten Wise Men, biological weapons with overwhelming symbological power meant to oversee the Nedian colonies. Doctor Lantis also had a daughter named Filia, but she was killed by the rebellion started by the Nedian colonies. In his grief, Dr. Lantis reprogrammed the Ten Wise Men from ruling the colonies to destroying it. After much destruction caused by them, including the death of Reema, the L'Aqua forces were able to stop the Ten Wise Men and banish them into space.
The destruction caused by the Ten Wise Men enabled the insurgent factions to organize themselves into a proper revolution against Nede. These wars led the population of Nede to hide itself from the rest of the known universe, not only afraid of the revolution, but also of its knowledge, especially on the field of Symbology, bringing more chaos to the universe. For these reasons, they created an artificial home, Energy Nede, and cast a potent Class 9 energy shield in form of a huge energy mass to prevent any interaction with the exterior.
In S.D. 366, the Ten Wise Men broke free of their prison, landing on planet Expel, and by their influence, the planet's orbit was changed, only for it to approach Energy Nede, in order to enable the Ten Wise Men to teleport themselves to their planet. Unfortunately, the clash between Expel and the energy mass surrounding Energy Nede caused the destruction of the underdeveloped planet.
The Ten Wise Men also gained possession of the Symbol of Annihilation, and turned Fienal into their own stronghold. With this power, they attempted to destroy the universe, but Claude C. Kenny and Rena Lanford, along with their friends defeated them. However, they were unable to stop the action of the Symbol of Annihilation, and by using the Symbol of Divinity, They were able to stop the destruction of the unvierse but the power of the Symbol of Annihilation is not stopped.Therefore, the powerful energy from the Symbol will be contained inside Nede and its Shield, leaving Rena Lanford, Chisato Madison and Noel Chandler, as the last of their kind. During that time they used the power from all cities including the newly dominated Fienal to bring back Expel to the Current time. After a few moments, the party is seen in transport bubbles leading to Expel while seeing the destruction of the Inner and Outer Nede.
Energy Nede lives on, however, when Rena decides to record the entire history of the planet with the aide of Chisato. The text follows Nedian history up until its 3,700,000,014th year when the party of the "Hero of Light" aided the Nedians in pooling their powers to defeat the Ten Wise Men and shift Expel through space and time. The history book took several years to draft, though it is unknown what happened to the book after it was completed.
