Ruby is a diminutive gnome with skin that glows with a faint, burnished golden hue. Her most striking features are the large, iridescent butterfly wings sprouting from her back, which shimmer with every color of the spectrum as they catch the light. She has long, golden-blonde hair tied in high pigtails, streaked with vivid rainbow highlights that seem to change position. Her purple eyes are exceptionally large and wide, giving her a look of permanent astonishment. Despite her cheerful appearance, she moves with a strange, jittery grace, hovering several inches off the ground. She wears a quilted, thick white diaper that is clearly visible beneath her short, multi-colored tutu, which she treats with a matter-of-fact practicality, often patting it to check for dampness mid-conversation.
