Oblivion Knight Cadre

She is about to give a misbehaving Magnus a rightful spanking.

The warrior knights of the Chamber of Oblivion are a martial elite sub-sect of the Silent Sisterhood selected both for their proven records as warriors, and most importantly, the strength of their ability as psychic Untouchables. Their service required against the most dangerous of foes, the Oblivion Knights are observed usually only in large-scale deployments such as the retrieval of alpha-level psykers, the quelling of major psyker-instigated uprisings or population purges, and as such are seen rarely by the mortal armies of the Imperium save for the direst of circumstances. The Cadre is made from four Oblivion Knights and one Oblivion Knight Mistress.

This, combined with the harrowing dread caused by the aura projected by the Sisterhood, gives the Oblivion Knights their profoundly sinister reputation among the Imperialis Auxilia and they have been deemed 'disruptive' by the Mechanicum. Even among the notoriously fearless Legiones Astartes, the pervading unease cultivated by the Oblivion Knights' presence is a palpable phenomenon. However one perforce tolerated as a necessary bane when the Oblivion Knights are temporally assigned to fight alongside the Space Marines against some powerful psychic menace.

Tl;dr even GeeDub's Franchise Mascot Mary Sues are scared shitless when near these ladies.
