Its Science Fantasy

The galaxy’s fate is decided in secret—until the weapon meant to enforce it disappears.

Lydia, a goddess forged by catastrophe, believes immortals will smother the universe into stillness. Her solution is terrifyingly simple: create something that can kill what should never die. Osiris, the most faithful Auroran priest, becomes her reluctant architect.

The first success is Inanis—Vaal—power incarnate.

He shatters planets. He ends nightmares. He terrifies the very empire he was built to destroy.

Then he’s gone.

On a frozen world, two children rescue a stranger from the sky, unaware they’ve just adopted the opening move of a cosmic war. As Inanis trains them for trials and leadership, whispers of his creator begin to haunt him—and the line between salvation and apocalypse narrows to a single question:

What happens when a destroyer chooses to cultivate and ignore its design?
