The planet now known as Virens was once Veridia Prime, established at an unknown time as a beacon of Terran expansion. It served as a vital research hub, dedicated to experimental xenobotany and rapid-yield agriculture. Its grand purpose was to develop technologies to end galactic hunger, a jewel in the crown of civilization.

In the catastrophic year of 3200 CE, the galaxy was torn apart by an event known as the Sundering. Veridia Prime's advanced Tier 4 containment fields, crucial for its experimental flora, failed instantly during this cataclysm. The genetically accelerated plants, suddenly deprived of their AI caretakers and exposed to the raw, chaotic metadimensional energies washing over the system, did not perish; instead, they began to evolve with terrifying speed.

Over the millennium that followed the Sundering, the planet's entire biosphere mutated into a predatory, semi-sentient Purple Jungle. This toxic overgrowth aggressively consumed the glistening megastructures of the collapsed civilization. It actively digested plasteel and circuitry, integrating these materials into its vast, expanding root systems.

The atmosphere itself transformed, becoming a thick violet haze of hallucinogenic spores and corrosive pollen. This lethal environment now renders unshielded human life unsustainable for more than a few minutes. Due to these extreme dangers, the Red Sun Dominion officially classified the world as Virens, designating it a Class X Tomb World.

Despite the strict quarantine enforced by a Dominion blockade, Virens continues to exert a mythical allure. Scans indicate its deep vaults still hold pristine Pre-Sundering agricultural technology and potentially caches of dormant Spike Drives. This promise of ancient riches attracts "Glory Hounds"—mercenaries, desperate scavengers, and those deluded by their own ambitions.

To date, many unauthorized dropships have breached Virens' atmosphere, but none are known to have successfully returned to orbit. The planet's surface is a graveyard of ambition, where the distress beacons of crashed ships chirp for days before the relentless encroachment of the vines inevitably silences them. Rumors persist in spacer bars of Sector 36 that the jungle doesn't merely kill; it assimilates, creating plant-based mimics of those who succumb to its toxins.

Virens remains under an official Ecological Quarantine, a testament to its lethal beauty and the dangers it still poses to any who dare approach.
