Ruby is a petite gnome with pale gold skin that glitters with a fine layer of pixie dust. Her most striking feature is a pair of iridescent butterfly wings that shimmer with every color of the rainbow. She has massive purple crystal eyes and long blonde hair with multi-colored tips she uses as paintbrushes. She wears a yellow tee shirt, a pink tutu that partially conceals her functional but childishly cute diapers thst she frequently wets or soils uncontrobaly, and custom ballet shoes.

Ruby is eternally optimistic and bubbly, viewing the world as a giant canvas waiting for color. She giggles frequently and approaches even the direst situations with a sense of wonder. Though her appearance is youthful and she faces physical challenges like her incontinence, she possesses a keen, scholarly mind and a deep understanding of the cosmos.

Ruby was born under the most vibrant aurora borealis her forest home had ever seen, an event that infused her soul with the prismatic energy of the upper planes. As a young gnome, she was drawn to the libraries of the Sage academies, seeking to understand the 'sky fire' that lived within her blood. Her physical condition of incontinence that she could never fix never dampened her spirits, instead, she integrated her needs into her whimsical style, seeing her dependency as just another part of her unique nature. While others studied from dusty tomes, Ruby learned to translate celestial wisdom into art, using her magical pigments to paint reality itself. She developed her signature weapon, a large brush that doubles as a blade and magic wand, to defend her colors from the grey mundanity of the world and protect those she cares about . Now, she travels as a wandering artist and scholar, manifesting her magic as fizzy, colorful potions and beams of hard light. She seeks to find the source of the great aurora, believing it holds the final secret to the ultimate masterpiece.
