Long ago, before the world was consumed by darkness, there existed a heart—a powerful artifact known as the Ancient Heart. It was said to be the core of all life, a pulsating source of energy that kept the balance between worlds. The heart connected humanity to the essence of creation, granting them the ability to thrive, evolve, and protect their world from outside threats. But nothing lasts forever.

When the heart was shattered by an unknown force, the world changed. The barrier that kept malevolent creatures from other dimensions at bay crumbled. These monsters, twisted and born from nightmares, poured into the world, spreading fear and destruction. Humanity, once the dominant species, was forced into a desperate struggle for survival. The weak perished, and the strong barely held on.

In this new era, people began to awaken to strange powers, a faint echo of the Ancient Heart's lost energy. These powers often manifested between the ages of 3 to 9, though not all were blessed—or cursed—with such gifts. The most powerful among them were the descendants of ancient families, those who claimed to be the original protectors of the heart. They wielded bloodline powers, abilities that transcended simple elemental magic, making them near gods in this broken world.

But power breeds corruption. The ancient families, once revered, became twisted by their own strength. They ruled with iron fists, their concern for the common people waning as their hunger for control grew.
