A dying world.A forbidden power.And two lives pulled together by a force neither understands.

Sora has spent her life hiding the truth burning inside her ? a truth capable of reshaping everything. When that power finally breaks through, it draws the attention of an immortal who was never meant to walk beside mortals again.

Nyx has watched ages rise and fall, bound to a purpose older than kingdoms. He is meant to end threats like her, not protect them. Yet the moment he finds her, something ancient stirs ? something that recognizes her in ways he cannot explain.

As the land fractures under gathering storms, Sora and Nyx are thrust into a conflict that reaches far beyond their world. Shadows move with intent. Forgotten forces wake from long silence. And the line between salvation and destruction narrows with every choice they make.

Their connection is dangerous. Their path is impossible.But the power rising between them refuses to be denied.

In a story shaped by cosmic forces, slow-burn intensity, and a looming threat that eclipses mortal understanding, A Vow of Rust and Starlight follows two souls bound to a fate that could save their world ? or awaken something far more devastating.
