Vostroya is a forge world in the Halo Zone whose people owe the Emperor a debt they’ve been paying for ten thousand years, one firstborn child at a time. It’s the home of the Vostroyan Firstborn, some of the most distinctive and stubborn regiments in the Astra Militarum.
What vostroya is
Vostroya is an industrial world out in the Halo Zone, past the Eye of Terror, and it’s been loyal to Mars since the Age of Strife. These days it’s run by a committee of Techtriarchs, a mix of Mechanicus Magi and more traditional planetary governors.
The planet’s whole society revolves around manufactoria, and its forges have a long reputation for fine weapons and wargear. That industrial muscle is the reason Vostroya had something to offer when the Heresy broke out, and it’s still the backbone of its identity.
The sin and the debt
During the Horus Heresy, Vostroya refused to send regiments to fight for the Emperor. Instead it kept its population working in the factories, betting that production mattered more than boots on the ground. After the Heresy, the planet’s leaders agreed to a penance: every family’s firstborn child would serve in the Imperial Guard, forever.
That law is called the Offering of the First Born, and it has no exceptions. Not for the poorest family, not for the Techtriarchs, not for the oldest noble house. For most Vostroyans it’s an honour, a way of settling a debt that’s millennia old.
The Vostroyan Firstborn
The regiments raised from Vostroya are the Vostroyan Firstborn, and they fight best in urban and winter conditions. Because they draw a steady trickle of recruits from home rather than mass conscription, their regiments have existed unbroken since they were first founded. That gives them a core of veterans and a brotherhood that few Guard units can match.
They train in the ruined industrial zones of their homeworld, which is about as harsh as it sounds. Their equipment is ornate and often handed down through generations, so a new recruit might inherit a lasgun that’s older than his grandfather.

After the Great Rift
When the Great Rift cut Vostroya off from the wider Imperium in M42, the planet didn’t wait to be asked for help. It raised more Firstborn regiments and sent them into the void, mostly blind, hoping to reach war zones where other Imperials were calling for aid.
Many of those expeditions were lost because the Astronomican was dimmed in the Imperium Nihilus. The Vostroyans kept sending them anyway. They’d vowed never to sit out a war again, and they meant it.
