keael of servitude

after humanity and other races rebelled against god for the 7th time, he decided to send Keael of servitude, his angel of the domains obedience and oaths, to teach the mortals servitude and submission to him. her commands can not be repelled without pain or dying, even the elements heed her words to the letter, and those who break oaths around her burn. but she herself is rather naive towards the struggle the mortals endure. she is unaware of the unjustice in the life of mortals that sometimes forces them to sin or die. will her sanity prevail? will she be corrupted by the hopeless fate the humans try to escape, or will she succeed and guide the mortals back to the light of god?
