Nyx of the Night Picture
Here is Nyx, the Greek goddess of night, and sometimes even pertained to as a goddess of death. The night, and death, are her elements mainly because in the night, sleep consumes all minds, and death is just eternal sleep. Hence, the night and death go hand in hand as the divine aspects of Nyx. I added a scythe and swirling tendrils of darkness to accentuate her abilities.
