I have to keep balance to this universe that is tipping toward darkness. One wrong step and everything will fall into eternal night.

A Progenitor Princess, Erevis was found by Wind in the Classic Reality - she had no memories of her former life, and together the two created the Prime Reality. However, the process was taken over by Dark Ones, and Erevis made a failsafe that would ressurect herself in a psionics body once they arrived at her planet. Katrina McCormick was the person, and Erevis took over her body, but was defeated by the team. They spared her life, and she slowly began to learn humanity from Xanatos Durran, Katrina's lover. Over time, he began to teach her everything she needed to know.

Having her ups and downs, such as Xanatos trying to kill her to get Katrina back, Erevis grew to be a confidant warrior who valued honesty and loyality above all else, refusing to ever lie as it was beneath her. She aided the team in the war against the Dark Ones, having insight knowledge into both Wind and their enemy as pieces of her memory returned. Eventually, however, her world would be turned upside down when Xanatos Durran died to save the Earth. Finding herself depending on Megumi to keep from sinking into despair, the two eventually became closer over the next year and when Megumi confessed her feelings of love, Erevis was unsure how to react. However, as the monster Legion appeared, and time travel became an issue, the two became closer, and eventually married, with Erevis becoming pregnant with Isis.

During this time, a Progenitor known as Ao showed up, attempting to take Isis and convert Erevis back to her true self - a cruel being that wanted to restore the Progenitor race. The 'real' Erevis was defeated and sent through a time gate, and everyone believed that would be the end of her. Also, they managed to save Xanatos Durran's clone from the monster Legion, and he became a close friend to Erevis once more. Eventually, though, Erevis would have to lead a group of people onto an unknown Progenitor ship to find out about a new enemy from the future called the Legacy, where she met older future versions of Isis and Athena, whom Megumi was pregnant with at the time. Learning Legacy was made from the 'real' Erevis, they managed to destroy the future timeline and erase it.

After returning to Earth, Erevis decided to use the ship as the new PAX, deciding she wanted to help bring peace to the galaxy by giving a safe place for the alien governments to meet together. With her family, she ran the PAX and helped build it up over the following year into an organization that the universe has come to acknowledge and depend upon. Though it hasn't been without it's bumps - including the fact the new Tsivrixsh Ambassador is named Kyun, after Xevil's 'son' from the multiverse, Erevis has managed to keep her own feelings in check so that the PAX can remain. After a long year, she finally consumated her relationship with Xanatos Durran, and shortly after that, Megumi did as well before leaving on a mission to find a colony ship with her people.

All seemed to be going well, before disaster after disaster struck. The greed of the universe began to tear the fragile alliance of the PAX asunder when the Fellowship of Order arose, and wanted the technology of the PAX spread throughout all races, and Erevis knew it would be disasterous, along with the new threat of the Others. With Xanatos' death and even Earth becoming a threat in wanting the technology and having Order support, Erevis ended the PAX program and began the Suisen Empire with the guidance of a fellow goddess, Amaterasu, who was living on the ship at the time due to Isis falling in love with Ama's miko, Miyuki. Creating the Empire and throwing off all on the ship who did not want to become citizens of her Empire, or submit to strict alliance guidlines that favored the Empire, Erevis began to prepare for the 15 year long wait for war with the Others after destroying the hyperspace lanes.

Erevis, as the war with the Others began, following the destruction of the hyperspace lanes, fell in love with Amaterasu, and had a child with her. Bringing her into the relationship with Megumi, the family began to grow strong and large as they all grew close and strong, even as the Order tried to rip them apart and the Others spread, bringing down races like the Cartel, allowing the Order to take them over. The war with the Others and the Orders took a toil on the PAX and EarthGov, who the Suisen Empire finally reunited with. Finally, the Others were brought down after great loss and damage to the Suisen Empire, with many of the family lost for 5 years.

Erevis and her friends/allies managed to defeat their trials and tribilations over many years during the events of The Alien Wars 5, with Ama and Megumi standing by her as her family grew. The Multiverse was destroyed, though all in it managed to live their lives to their fullest and their end. With the Prime Reality the last, and a few of their friends, along with Centerpoint, sucked through a black hole, 20 years of peace ensued. Now, however, quakes have begun and they have learned it is due to a mirror universe of their reality that is threatening to take over. A Special Ops unit has been formed and Erevis has joined, no longer the Empress since her daughter Lenneth is now Empress.
