This is Luna. My entry. There is a ton of detail to her so I will explain to my best ability. Oh, and the the timer is all-knowing for the most part. I spent a ton of time on this! More like three hours. :3 Stars mean go to the bottom for additional info. You can make up your own history.
Starting with her head.
Eyes: Lunas eyes are aqua, representing her mental stability, telling you that she is very, very kindhearted and is willing to listen to anyone.* Underneath her eyes are a sort of blue stream; these are tears frozen in time never going to leave.
Head and Ears: The white is just there. Don't ask me why. She was born with it.
Legs: On her Back left leg and front right leg is complex pattern of purple said to be stale blood but to her, it's otherwise. Luna says that the patterns are on her legs to symbolize her mother, as she had the same markings.
Front Quarters: Nothing special, just the white is there again.
Hind Quarters: The top of her hind quarters is another white patch but a sort of light purple glow is above it. The glow isn't attached, but it's there and it's staying. The moon is where her name comes from. Over the moon is a sort of fog darkening the moon to where it is hardly seen.
Body: Nothing except the belly is dark purple.
Tail: Nobody knows why the bottom of her tail is blue, but the edges of it glow blue like the spot on her hind quarters.
*Blue is the color of the sky and sea. It is often associated with depth and stability. It symbolizes trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven.
