Achlys

Achlys (Ancient Greek: Ἀχλύς; "The mist over eyes") was the daimona personifying the mist that fell before the eyes preceding death. She may also have been the goddess of poisons. She was also a personification of the Eternal Night, and is believed to have presaged Chaos. According to Hesiod, she was the personification of misery and sadness, and as such she was represented on the shield of Heracles: pale, emaciated, and weeping, with chattering teeth, swollen knees, long nails on her fingers, bloody cheeks, and her shoulders thickly covered with dust. She may have been a daughter of Nyx, though it is not stated anywhere.
