A fallen angel, in chains. The image belongs with the 'gray man' images. According to apocryphal texts, an entire choir of angels, the Gregorii, fell from grace when they decided to mate with human women. Their offspring were called the 'Nephilim', which means something like 'oblivion'. It is said the the Nephilim got their name from the expression 'Chained to the pillars of Nephilim', meaning that they were locked away in oblivion... Pencils/Pen - Colored in Photoshop.
