My remarkable children, you must be beacons for the future, lighting the way for Akiridion-5.
Queen Coranda to her children, Aja and Krel, during a flashback[src]

Akiridion-5 is an energy-based technological planet, inhabited by blue energy beings called Akiridions.

It is currently governed by House Tarron, before and after the planet was invaded by the tyrannical, exiled general, Val Morando.


From outer space, the planet has multiple non-natural occurring rings and four satellites orbiting the planet. Due to the planet being gaseous and having no solid ground, gravity keeps every building floating in the air.


Long ago, an ancient Akiridion deity named Gaylen was said to have god-like powers within his core, which was capable of creating and destroying entire planets. With the strength of his core, Gaylen crushed the stars and used its dust to create Akiridion-5. However, he became greedy with his power and almost destroyed the planet. Luckily, an ancient royal Akiridion named Seklos built a cannon and, using all of her life force from her core, defeated Gaylen and hid his core, for it was far too powerful for anyone to possess.

For hundreds of keltons(years), Akiridion-5 stood divided between two houses. The House Akram of Queen Coranda's ancestors and House Ventis of King Fialkov's ancestors. They celebrate the joining of the two great houses into House Tarron on the day of Princess Aja and Prince Krel's in-waiting coronation to declare the heir to the throne be ready and good.

However, General Morando led a coup that resulted in the king and queen losing their physical bodies and their heirs being forced to flee. While Morando consolidated his powers and began hiring bounty hunters to recover the royal life cores and capture or kill the heirs, a resistance formed with the goal of restoring House Tarron to the throne.

Despite Morando's hostile takeover, public worship of the royals threatened to spark open rebellion. Desiring to destroy the populace's hope, Morando sent his first Omen Blank to Earth to put an end to House Tarron. However, Princess Aja's fierce resistance merely inspired the populace before she and her brother encouraged their people to never surrender. With the royals having foiled him again, Morando prepared to launch a full-scale invasion of Earth.

With the sacrifice of the king and the queen's royal life cores, Morando and his invasion force failed after obtaining Gaylen's Core. While Krel decides to stay on Earth a while longer, Aja returns to Akiridion-5 as its new monarch.

Following this convention, Earth is named Sol III. Likewise, Akiridion V (or 5) would be the fifth planet in the planetary system of the star Akiridion.
