#Tl:dr the excorcist unit is essentially a murder cult

[deathinfeathers]

The exterminators are a distinctive choir of their own but they did not come about in the same fashion as the rest of heaven's native born denizen. They are a relatively small, self-contained society, one which the heavenly host has kept strictly segregated from the rest of the celestial kingdom for several millenia. Every exterminator who ever was has been born and raised inside the compound serving as the excorcist unit's base of operations. This is done namely to keep the annual purge under tight wraps and to ensure that this innately violent, combative and unruly caste of people does not cause a disturbance inside the rest of heaven's picture perfect society.

They are composed entirely of women and girls, governed by an exclusively male body of supervisors who's sole objective is to methodically break each member of the commune in via an elaborate system of indoctrination which starts as soon as a nestling exterminator is fit to attend their junior academy. The ultimate intent is to create perfectly obedient, perfectly subservient, perfectly objective oriented soldiers who possess very little in terms of superfluous opinions or emotions (save for that which is systematically instilled in them). If simple brainwashing does not do an adequate job at scrubbing any unwanted thoughts and inclinations from their minds a much crueler system of punishment and reward is implemented in order to achieve the desired results. The herd is culled once a year in order to get rid of any stragglers who refuse to fall in line.

Winners do make up a small percentage of the excorcist population; If a mortal soul causes a great enough disturbance in heaven they will be sent to serve alongside the true-born members of the unit for the rest of their immortal lives. They are usually considered to be weak and are generally shunned by the women of the compound.

Adam sits at the very top of this totem pole, though he is more of a figurehead, in essence, who's involvement with the day-to-day going-ons inside the base itself is little to none until it's time to rally the troops into action. Lute on the other hand is much more wrapped up with the actual machinations of the system and travels to the compound every Sunday to conduct sermons and lead various combat courses for the fledgling members of the commune. She has spent over nine centuries of her 1000+ years of life serving directly under Adam. For somebody of her ilk, she leads an exceedingly cushy lifestyle thanks to her association with him. That's not to say she was, by any means, spared the harsher reality of what it means to be an excorcist before she came to be regarded as an extension of the commander himself.
