Changes

[[Miriael Sabathiel]] was a [[Sister Superior]] of the Order and is the only sister acknowledged to have willingly fallen to [[Chaos]]. A Canoness of the Order, [[Olga Karamanz]], was murdered by Miriael when she tried to apprehend her, even as the Canoness proclaimed a desire to help Miriael.{{Fn|5}}

===Third War for Armageddon===

The forces of the Order have been seen heavily in the [[Armageddon]] sector, during the [[Third Armageddon War]]. They protect lone worlds from attack and strongly regulate the lives of those under their jurisdiction, and that of the [[Ecclesiarchy]]. Their power comes from the great [[Sanctorum of St. Katherine]] which is built within the high walls of [[Hive Tempestora]] which is also a centre for Ecclesiarchal activities on Armageddon. Their positions were assaulted by [[Ork]]s emerging from vast submersibles emerging from the Boiling Sea. The Sisters were the front-line defence of Hive Tempestora but due to the sheer surprise and ferocity of the Ork attack, many units were caught unaware and floundered. This allowed the Orks to take control of the majority of the underhive within a few hours of landing{{Fn|15}}.
