I am so happy that I found that photo on pixabay, it is so similar to the one I have in my head :) Yes, she has wings made of trees and it looks like she is holding forest on her back. Her name is pronounced like you would read that word in Spanish (word in Spanish for "she"). Ella is something like a portal into that world and a storyteller at the same time, all the stories and all the worlds are on her back, one in every leaf.

Sapphire is pure color, well, she is color itself and what color can do, so can she, but that will be revealed later, no spoiler alerts sorry, hihihi.
