Sentinels of Vigilance

The Sentinels of Vigilance was a Loyalist Space Marine Chapter of the 3rd Founding created in the early 32nd Millennium as an Ultramarines successor chapter. They served dutifully from their Fortress Monastery the Acre Umbra until their ultimate destruction at the hands of Kal'cerus The Dreaded, their fortress and world destroyed and christened a Daemon World under it's new terrible ruler.

Chapter History
Though technically created during the 3rd Founding, the Sentinels of Vigilance have been based upon Iotera since the Great Crusade itself, the 34th Chapter of the Ultramarine Legions stationed to guard a dark and terrible secret. It wasn't until much later, after the mortal wounding of Roboute Guilliman, that they were officially formed into their own chapter and granted a greater autonomy to conduct their own affairs and continue fulfilling their longstanding oath.

A Dark Secret
In the crystal mines of Delteka the final battle for the planet was fought. The Ioteran rebels made their last stand here, twisting and windy caves made entirely of crystal, making it a devastatingly difficult stronghold to take. Each corridor was taken with a bloody toll. The war council debated collapsing the mines and burying the rebels, leaving them to starve, but troubling reports of the rebels fighting with a fervent rapture in their desperation and other, unsubstantiated rumors of squads going missing, leaving only by bloody claw marks and rent armor. Something was amiss and Guilliman intended know the cause. So it was that the slow, attritious fight through the mines continued until finally the main sanctum within the mines was all that remained. After several days of intense fighting the sanctum itself was taken by a combination of the Ultramarines and Emperor's Children. At the center of the sanctum an altar of devious design constructed out of the naked corpses of many of the worlds own rebels sacrificed to it. At each of the four corners of the Altar was a different type of sacrifice. Four human corpses whose skeletons had been pulled out of their bodies and repurposed into a pedestal hosting a skull doused in blood. Finally at the center of the altar, a red pulsating crystal that emanated a horrifying presence.
