Coven of the Blessed Maiden: The most special Coven in the Host. They recruit only from the captured sisters of battle, from the ones that can't take their new life of abuse and slavery, the ones that listen to the voices in the dark, the ones that make a pact to get out of bondages. They get out, true, but their soul pays a heavy price for freedom, they become posessed by a Deamonette of Slaanesh, forever bound to service to the Daughters and the Apostle.

BATTLE COVENS

Coven of the Poisoned Chalice: The Poisoned Chalice is one of the support Covens, assigned to work as a combined arms team, alongside astartes, armoured formations, titans, brotherhood warriors, aerospace assets, and so forth. The Poisoned Chalice is equipped with (light) PA and come equipped with an over-abundance of melta weapons (although there are never eunuch to meet their needs).

Coven of the Bleeding Heart: Sister Coven to the Poisoned Chalice. Due to a shortage of melta weapons the Bleeding Heart must make do with other heavy weapons - missile launchers, lascannons, heavy bolters, and the like. Which is quite all right with the Domaina, as she greatly prefers killing at long range.
