Also known by the "endearing" nickname of 'chicken wings' by Cheryl. Ellie was my first OC and one of my favorite personal characters in general. She lost her left wing when a prototype drill collapsed the cave she was in. Now she uses a mechanical replacement. She can't fly, but she can glide and could get "towed" through the air by another pegasus.
Many thanks to Meto30 for heavily inspiring the wing design and her cutie mark.
