The War for Earth

The War for Earth, known in Rikutsaren as the Urélnear and in Lithon as the Naer Urtélaet, was the longest and deadliest war in Earth's known history. Billions of Lithon and human soldiers faced off in battlefields across the planet, primarily in Siberia and Scandinavia. The war lasted for 378 years, and every human family tree on Earth today has an ancestor who fought in the war. The human death toll isn't known, but Smenaer estimates it to have been more than 10 million, almost 25% of humanity at the time. Meanwhile, billions of Lithoi were created with the sole purpose of fighting and dying in the war.

The Lithoi are a colonial species, taking every planet in their path and warping it to their benefit. Earth was merely their next target. But many had endured enough oppression, and rebelled. Though these rebellions had been ongoing for centuries already, the war itself began sometime around the year 3,200 BCE. This is when a rebel faction called the Knights of Anthos attacked and successfully overtook multiple Lithon bases on the planet. The faction was extremely successful in causing enemy soldiers to betray their side, mostly due to the high resentment that most lower-caste Lithoi had towards the Theongorai. Therefore, the rebels had a huge advantage from the start. When Lithon forces attacked the rebels, they were able to meet with equal or greater power. Special spies called Valugiric ("changers") were dispatched to dispel propaganda to enemy soldiers. The Mae component of Óasmae was a Valugir.

The ensuing war was successful in driving off the invading Lithoi, but at a great cost: nearly every Lithon on Earth was obliterated by a powerful and coordinated attack by the Theongorai. Only a handful of soldiers survived, including Smenaer and Óasmae, who were now close friends from the war. Meanwhile, Anthos and her closest confidants also survived due to her powers, and they disappeared into obscurity for the following few millennia.

Song of the Theon
The Theoncas (literally "Song of the Theon") was the infamous single attack that ended the War for Earth. The technology used was unknown, but somehow the Theongorai had obtained a way to obliterate Lithoi on the scale of an entire planet. The attack lasted merely 15 seconds, and in that time all Lithoi on the surface were vaporized. According to The Empresses, humans of the time said the attack was extremely bright, and the faint sound of singing could be heard beforehand.
