Original drawing of a demon I just called 'Cide for a while. Recently came up with a better name. The drawing itself is not new, but I've also never posted this concept up before.
In the domains of death one demon covers killing of all kinds.
Murder and suicide.
Same demon, two different mouths.
He/She/They is/are the voices one hears. At first, if still sane, the words seem like their own thoughts. But if one goes insane he/she starts hearing the whispering demonic voices for what they truly are... in many tongues, and in many kinds of voices until they build up and overwhelm in a rising cacophony impossible to ignore or drown out.
They demand death of someone by your hand. If not someone else, then yourself.
