Utterly colourblind after an injury to his temple, the Netherwing can change his shape, but his shifts of hue only produce disarming greyscale results. The few who witness his change to elven form seem to prefer him in his native colours, given the current connotations of skin and hair stripped of natural pigmentation.
The ribbons of energy that exude from his scalp are involuntary and shift angle with tension. While he could shift his features to something less beaky, he prefers to have a lot of nose in his range of vision. It feels more normal.
