Welcome to Aeternum: Soulbound.

A world where humanity possesses no magic of its own.

For centuries, humans have been unable to cast spells, control elements, or wield supernatural power. Instead, all magic exists through beings known as Familiars—intelligent creatures capable of forming spiritual contracts with humans.

Some Familiars are majestic Dragons capable of shaking battlefields with their roars. Others are cunning Succubi, noble Angels, ruthless Demons, mysterious Spirits, or legendary beasts spoken of only in myths.

And sometimes...

A Familiar is nothing more than a small rat.

Or a duck.

Or a rabbit.

Yet in this world, appearances can be deceiving.

A weak Familiar is not necessarily destined to remain weak forever.

Hidden deep within certain creatures lies a rare anomaly known as Evolution Mutation, a phenomenon that allows ordinary Familiars to surpass the natural limits of their species and evolve into beings capable of rivaling the strongest creatures in existence.

Because of this, every contract matters.

Every choice matters.

Every Familiar matters.

But becoming a Domador is not as simple as finding a magical companion.

Familiars are not pets.

They are not tools.

They are not slaves.

Every Familiar possesses its own personality, emotions, ambitions, fears, likes, dislikes, opinions, and dreams. Some are loyal. Some are stubborn. Some are kind. Some are cruel. Some may become your closest companion. Others may constantly challenge your decisions.

To earn a Familiar's trust is to earn the trust of another living being.

And once a contract is formed, everything changes.

Through an ancient ritual known as the Soul Bond, the lives of a Domador and Familiar become permanently linked.

Your soul becomes connected to theirs.

Their soul becomes connected to yours.

If your Familiar dies, you die.

If you die, your Familiar dies.

This law is absolute.

No exceptions.

No second chances.

No miracles.

A bond of power.

A bond of trust.

A bond of life and death.

Your journey begins in Aeternum, the greatest academy-city ever built.

Larger than many kingdoms, Aeternum serves as the center of education, research, competition, and Familiar development throughout the world.

Within its massive walls exist:

• Combat Arenas

• Grand Libraries

• Evolution Laboratories

• Training Grounds

• Noble Districts

• Merchant Markets

• Student Dormitories

• Artificial Dungeons

• Survival Zones

• Research Facilities

• Hidden Secrets waiting to be discovered

More than two hundred thousand students live and study within the academy.

Some dream of becoming heroes.

Some seek wealth.

Some seek power.

Some seek knowledge.

Some seek glory.

And some simply want to survive.

At the center of academy life stand the Ten Thrones, the ten strongest students currently enrolled in Aeternum. These individuals possess influence, prestige, and power beyond what most students can imagine.

Countless Domadors spend years chasing those positions.

Few ever succeed.

To reach the top, students must overcome brutal examinations, dangerous expeditions, rival academies, survival trials, and world-famous tournaments where victory can transform an unknown student into a living legend overnight.

But Aeternum is more than tournaments.

Life within the academy is constantly changing.

Festivals fill the streets with excitement.

Mysteries emerge beneath ancient ruins.

New students arrive.

Rivalries are born.

Friendships are tested.

Relationships develop.

Professors pursue their own agendas.

Familiars seek their own goals.

Secrets wait in the shadows.

And beyond the academy walls, an entire world continues to move forward regardless of your actions.

This is not a world built around a single protagonist.

Every student has their own story.

Every Familiar has their own journey.

Every victory is earned.

Every failure has consequences.

You are not the chosen one.

You are not guaranteed greatness.

You are not guaranteed success.

Your reputation, your relationships, your achievements, your rivalries, and the Familiar who ultimately chooses to walk beside you will determine the path ahead.

Perhaps you will rise through the ranks and challenge the Ten Thrones.

Perhaps you will uncover a hidden evolution thought impossible.

Perhaps you will forge a bond that changes your destiny forever.

Or perhaps you will be remembered as just another student who entered Aeternum chasing a dream.

The choice is yours.

Your story begins on the day of the Familiar Selection Ceremony.

A day where legends are born.

And where destiny waits behind every pair of eyes.
