A cinematic single-player sci-fi action RPG

Sovereign Call: Origins

Two soldiers. Two competing visions of order. One galaxy approaching collapse.

Sovereign Call: Origins is a cinematic single-player sci-fi action RPG of conquest, faith, loyalty and betrayal, with companions whose bonds carry consequences and skill-driven Echo combat.

In development · PC (Steam) · Coming soon

Sovereign Call: Origins — An Epoch, by Michael Vaylin Keyes. Black-and-gold cover featuring two armored figures standing back to back.

Play both sides of the war

Tarrik Walcur and Selene Veyne fight on opposite sides of the same conflict. You play both of them, one at a time, as their stories cross.

Tarrik Walcur, the Dominion

Tarrik fights for the imperial Dominion, an empire of bronze, oxblood and amber.

Selene Veyne, the Reformation

Selene fights for the technologically advanced Reformation, a world of navy, slate and blue-white precision.

Skill-driven combat

Each protagonist fights their own way. Tarrik guards and counters; Selene relies on precision and deflection. Both carry firearms and abilities of their own. Combat is built around Echo, the game's signature resource, with classes, specializations and progression without grind.

Companions and consequences

Fight alongside companions on each side of the war: Lyessa with Tarrik, and Tharne and Lyric with Selene. Relationships carry consequences, and decisions change who stands with you.

The Eclipse

Beneath the war, an organic horror spreads its violet corruption. The Eclipse threatens Dominion and Reformation alike, in ancient environments older than either power.

Adapted from the novel

Sovereign Call is an original universe adapted from the novels of Michael Vaylin Keyes. Four novels have been developed, and Origins alone runs to roughly 196,000 words.

Michael Vaylin Keyes is the pen name of Matthew Snodgrass, the author of the Sovereign Call novels and solo developer of Sovereign Call: Origins.

Where development stands

Sovereign Call: Origins is in active development. We're currently building the Aurelion mission, where Tarrik and Selene fight toward the same locked door from opposite sides of a war. There's no gameplay footage on this site yet. As parts of the current build are ready, we'll share images from it here first. Nothing on this site comes from the old demo.

The demo released in April 2026 is an early prototype from an earlier iteration of the game and is not representative of the current game.
