Planetary Status & Overview
Teruxyne lies under a perpetual quarantine, designated as both a Dead and Forbidden World. It is locked down by Imperial decree—no entry, no exit. Even the strict Administratum and Inquisition enforce the blockade due to the extreme dangers lurking beneath its surface. wh40k.lexicanum.com+7wh40k.lexicanum.com+7ultima-tectum.com+7
The Sinner’s Plague
- In the early 41st Millennium, Magos Biologis Heretek Sar Resque unleashed a horrific bio-engineered plague known as the Sinner’s Plague across the Drusus Marches. wh40k.lexicanum.com+10calixipedia.fandom.com+10ultima-tectum.com+10
- Teruxyne’s colony was ground zero: the infestation mutated animals and colonists into grotesque abominations. Inquisitor assessments describe “nightmare corruption of the flesh beneath a dark night sky.” calixipedia.fandom.com
- By 722.M41, the hive colony was eradicated in a single violent purge. Remaining mutant survivors were either executed or left to wander in herds under the so-called Transfigured. ultima-tectum.com+3calixipedia.fandom.com+3dark-heresy-rp.fandom.com+3
Quarantine & Forbidden Status
- Teruxyne is classified under Imperial law as a Quarantined/Forgotten World—too dangerous to settle but too significant to destroy. wh40k.lexicanum.com+3calixipedia.fandom.com+3wh40k.lexicanum.com+3
- The planet remains off-limits to all but the highest levels of the Ordos, which alone hold clearances for missions into the ruinous hive-spires. The surface is littered with mutant remains and ruptured buildings, barred by quarantine warnings.
Inquisitorial & Mechanicus Context
- Sar Resque was tried and excommunicated by a Mechanicus tribunal in 710.M41. Her subsequent escape and plague campaign went unchecked until late efforts by the Cult of Sollex and Inquisition intervened. wh40k.lexicanum.com+5dark-heresy-rp.fandom.com+5anyflip.com+5
- Though Resque vanished into the Shadowed Marches, fragments of her work remain—mutants termed First False Pattern, deliberate steps toward a warped “Transcendence.” dark-heresy-rp.fandom.com
