Couldnt resist drawing the starry-eyed... well Star from the original concepts!
I heard somewhere their name was Earendel, soooo Im going to roll with that and call them Earen for short :)
Backstory Idea
Earendel is a celestial being, born in the farthest parts of the galaxy. Even if they were surrounded by stars like them, they felt alone as they could not shine as bright as they did. However, they found solace by watching the humans live their lives.
They always had a fascination with humans, and grew evermore curious. This is where they learn about humans holding wishes in their hearts, and have the drive to make them come true without magic with their own faith and determination. They inspired them to take matters into their own hands. Then one day, even in the deepest, darkest parts of space, they heard an earnest wish sung to the stars awaiting for a reply.
A wish asking the heavens for something better than the reality created by the king and queen. More than willing to help, they raced down to earth to meet the girl who made this wish and help make it come true.
Motivation
They thought in the bigger picture, they were just a tiny speck in the sky with no significance. Their wish was to leave their mark and make a difference, so they too can shine bright. By the end of the movie, their new wish is to stay with their new friends and true love, Asha.
