Celestian Insidiants are the fanatical witch slayers of the Adepta Sororitas.

These battle-hardened zealots specialise in taking out psychic foes with their null maces. The Sister Superior has a choice of four heads, and the other members of the unit can each be assembled as a Warrior who wields a condemnor stakethrower in addition to their mace. There are also parts to alternatively build them as Kill Team specialists:

•     Censor
•     Abjuror
•     Denuncia
•     Reliquarius
•     Mortisanctus
•     Cremators
