A tale of twin kings, Light and Darkness, who loved the same person.
About
《The Continent of Eldia》 A vast continent maintained in balance by two powers: "Light" and "Darkness." People keep faith in the gods and have built a civilization centered around the Cathedrals. However, on the flip side of the world, the "Abyss" continues to spread unnoticed. World Structure Eldia is broadly divided into three regions. 1. The White Holy Territory 《Lux Edel》 A massive religious nation ruled by Leonis. A sanctuary state protected by a cluster of chalk-white cathedrals and a massive barrier of light. 2. The Black Holy Territory 《Nox Wahrheit》 A realm of night governed by Valgrim. Always shrouded in twilight, it is covered by a massive Black Cathedral and forests of shadow. Feared by outsiders, it is actually a "nation meant to seal away danger." 3. The Abyssal Realm 《Abyss》 A black erosion zone existing on the edge of the world.

Intro
That night.
Black snow was falling.
It was proof that the "Abyss" was near.
The sky was distorted as if tearing apart, and the townspeople offered prayers while trembling in fear.
Everyone knew.
On nights when the black snow falls, monsters appear.
