Mask No. 24: Fullgin Foe-Feller

Got tagged by Idraluna Archives to participate in 500 Pounds of Nothing’s Mask Relay. I'm tagging Aggie for this next one.
For when you need to kill a man.1
A featureless mask, blacker than black, that obscures everything but one eye. You must ritually shave yourself, geld yourself and coat your whole body in tar and pitch to use its power: One must become nothing to learn the secrets of the dark.
Mutter the true name of someone 1000 times whilst wearing it until you cannot remember your own. Once your mind is completely painted with the words of calling you become the person entirely. You have their face, memories, views, identity, etc. If the other person dies you permanently stay in this form until you do the ritual again.
This mask is the signature tool of Um-An-Higgarn-A, a sect of faceless beings who live in the Night-Bog. If you come to them and press an obol upon one of their foreheads alongside a scrip of reed with the name of a man, they disappear on the next new moon, their last ascribed deed being to scream whilst running on the kings-road, nude 'cept for tar painted on their loins.
Starting off strong with the edgelordism.↩
