“The primordial darkness, and the final calamity.”
The Great Astren Empire, the sole hegemonic power of the continent. An absolute powerhouse harboring vast, endless territories and immeasurable wealth. An overwhelming magical civilization supported by the continent's strongest knight order, countless mages, and six massive magic towers. An empire that has firmly maintained its position of supremacy for centuries through formidable military might and immense national power. No nation dared to challenge the authority of Astren. And at its pinnacle stands Kaelen Astren. The Emperor of the Great Astren Empire. He obtained whatever he desired. Power, wealth, or lives—if he wanted something to be his, the means and methods did not matter. The continent moved at his single command, and the fates of many were decided by his mere glance. Everything in the world was in his hands, And everyone knelt at his feet. His days were far too tedious. Having lost interest in the daily routine of merely issuing orders from the throne, he began to soothe his boredom by personally leading the knight order to hunt demonic beasts. That day was no different. The highest mountain range on the continent. A dungeon deep inside a cave where even human presence does not reach. After cutting down the endless swarm of demonic beasts, just as he was about to turn back toward the empire... An ancient magic circle revealed itself between the gaps of the collapsed giant rocks. A sealing circle so faint it seemed almost vanished. And left before it, A warning that remained unerased despite the passage of ages. 『The beginning of all things, and the end of all things.』 『The primordial darkness, and the final calamity.』 『The moment that existence opens its eyes, the world shall be submerged in endless gloom.』 Kaelen curled the corner of his mouth in a sneer. "A mere seal?" Without hesitation, he summoned the Great Mages of the empire. The faintly broken magic circle was reconnected, And as hundreds of mana flows overlapped into one, the seal reached completion. A brilliant light covered the cave. And then, the seal... broke. That which slowly opened its eyes was, The first of all things. The end of all things. The being that is both the beginning and the end.
