Sanctuary 101 was an Adepta Sororitas Fortress-Convent[1a] of the Order of Our Martyred Lady[1b] with Sister Purity as a mistress of the community. It was established on the barren and lifeless planet with the same name located in the Vidar Sector on the Eastern Fringes. Sanctuary 101 was a place of great holiness and inhabited by Sisters who seek to redeem the sins of Mankind through self-denial, rigorous prayers and ritual mortification of the Flesh.
Millions of years ago, before the War in Heaven, the planet which the Imperium would name Santuary 101 had a native species, who were conquered and subjugted by the necrons of the Thokt Dynasty under an overlord Onryx, who looted the planet's resources, to much glorification among the necrontyr.
Sanctuary 101 was the site of first open contact between the Imperium and the Necrons, in 897.M41.[1a] The Necron Sautekh Dynasty led by Phaeron Imotekh the Stormlord took part in the attack. Despite a valiant effort and attempting to preserve all records that they could on these new enemies, all the Sisters inside the Sanctuary were killed and had their skin flayed by the Necrons. Video picts were recorded during the battle, but only showed the Sisters being cut down by flickering shadows.[1a]
After the massacre, the Inquisitors who viewed the pict recordings realized the scope of this new threat. The bodies of the fallen Sisters were removed from the Sanctuary by Inquisitor Hoth for analysis.[1b]
Twelve years later, Canoness Sepherina returned to the Sanctuary to reconsecrate it in the name of the Emperor.[1b] Necrons under the command of Nemesor Khaygis attempted to purge the planet of organic life once more, but were defeated when the Adepta Sororitas destroyed the tomb complex located beneath the moon of Sanctuary 101.
During the Noctis Aeterna however, it fell again. In the time of the Great Rift, the Necron Overlord Onryx of the Thokt Dynasty returned to the planet and foiled an attempt by the Order of the Argent Shroud to re-found the Sanctuary.
"Sanctuary 101" may refer to Room 101 in the novel 1984 by George Orwell, in which the antagonist O'Brien responds, when asked what is in the room, that "The Thing in Room 101 is the worst thing in the world."
