The Eternal Radiance Era

In Galactic Year 227, the "Dark Tide" devoured every star system.

Every civilization reached its peak, then came to an end. New life emerged from the ruins, and destruction and rebirth began another endless cycle.

No one knew that the energy everyone had tirelessly sought to keep interstellar society running required human beings as its vessels.

Energy always runs out eventually. So who among the people would become the so-called vessels?

Could they take control of their own destinies?

The struggles for power within the royal family.

The choices and compromises of merchants...

A thousand different kinds of love, each with its own unique charm.

What endings will each of them meet?
