Bloodbound Codex: I Grow Stronger in Secret

Atlas was a commoner from Ormolio’s outer slums.

When an Eternal-Class Ruin appeared after a thousand years, the Royal side needed someone to enter first and trigger whatever was inside. They did not send a noble heir, a trained Revenant, or someone with value.

They sent Atlas.

He was meant to enter first, awaken the Boss Monster, and die there.

But inside the lower section of the ruin, Atlas found a sealed relic called the Bloodbound Codex.

The Codex does not give him power directly.

It lets him WRITE his own growth.

Strength: _ _ _

Stamina: _ _ _

Agility: _ _ _

Spirit: _ _ _

Later, it records Traits, Bloodlines, Talents, and other things Atlas does not understand yet.

The rule is simple. The Codex needs blood.

With the Sanguis Stylus, Atlas can use blood to write numbers into his Attributes. Stronger blood allows better growth. Monster blood can also be absorbed by the Stylus, and certain monsters leave behind Traits that Atlas can permanently assimilate.

Because of this, ruins become important to him.

Monsters are not only enemies anymore. Their blood, bodies, and abilities can become resources for his growth.

The Royals believe Atlas died inside the Eternal Ruin. The nobles never cared about him in the first place. But Atlas survives, leaves Ormolio, hides his real progress, and starts using ruins to grow stronger without exposing the Codex.

He does not want to be noticed, does not want to serve nobles.

He does not want to become someone else’s tool again.

For now, Atlas only needs three things.

Power.

Information.

A way to leave behind the life where people like him are used and thrown away.

And when he becomes strong enough, he will return for the people who sent him into that ruin - Revenge.
