Ingris. A prosperous and beautiful planet where humanity thrived daily, was plunged into despair in a single day. The opening of dimensional gates to other worlds triggered an invasion by the highly advanced alien faction, Vulgus, and Colossi armed with formidable weaponry.

The Vulgus that appeared on Ingris seized control of various parts of the planet in search of something. The Colossi were on a similar mission. Initially believed to be hunting the surviving humans, it soon became evident that they had a different objective. Humanity's enemies were after the infinite energy source known as the Ironheart, said to exist on Ingris.

Despite the devastation, humanity still had hope. The Vulgus scientific faction, the Magisters, betrayed their legion and sided with the vulnerable. With their technology and resources, humanity abandoned swords and shields in favor of guns and gunpowder. Remarkably, the Magisters awakened a mysterious power dormant deep within human genes. This genetic material, called Arche, was documented in the ancient texts of Ingris and represented the power of ancestors who perished for unknown reasons.

Now, armed with newfound power, humanity strives to protect Ingris, carrying forward the mission of their fallen ancestors. The Vulgus leader, Karel, invades Ingris, driven by the mission left by his own forebears. The Colossi, fueled by the cursed commands of their predecessors, continue their relentless assault on Ingris.

Everything hinges on the 'First Descendants' linked through Arche.
