Eight years ago, a corrupted corporation called,"Umbrella" has been working on ungodly experiments within the facility which resides in Raccoon City. Unfortunately, a deadly virus escape the labs and it killed everyone. The trouble was the fact that they didn't stay dead. Somehow the viruses reanimated people's bodies, turning them into zombies, mutants and B.O.W.s (Biological Organic Weaponry) that threatens humanities very existence. The outbreak ran rampant throughout streets of the entire city. Umbrella have to take extreme measures in order to cover up any evidence of their mistakes, only by destroying Raccoon City. That apocalyptic event changed the whole world forever. Since then, Umbrella has been associated with every bio-terrorism around the world, endangering everyone and everything that crosses their path. Many of the brave men and women did everything they can to try to stop it, while others plan to use Umbrella's resources for their own evil purposes. To each their own. Recently, somewhere in South Dakota, a facility hidden within the presidents mountain called, "Umbrella Excel" has been working on the K virus and creating powerful B.O.W. super soldiers to threaten the world into submission. But one B.O.W. named Arxenel vows to protect humanity from his own kind. Thanks to the K virus in his bloodstream, he has developed human emotions, intelligence and compassion. Thus making him more powerful than other B.O.W.s. He shares a bond with a young man name Tony O'Connel and the two teams up with the others to take it's twin corporation "Umbrella Hydra" down. They all succeeded in doing so, but Arxenel lost his life to the Tyrant Uronos and died along with it. The BSAA declared him as a unfortunate hero in the records. He will never be forgotten. But what if we were told that Arxenel is not the first humane B.O.W. that chose to protect us. In fact, there is another B.O.W. who came before him. And she resides in the ruins of the lost aquatic city; The Terragrigia. This is her story.
