Appearance:
Shira is a slender and sleek silver-white tabby she-cat with bright blue eyes that are much like pools of pure water and has a long, sleek tail. She has white paws and face, and a striped silver tail and silver tail-tip.
She only wears a tan-colored cloak and a dark brown satchel when traveling through the desert. But when removed, she could be seen wearing a simple copper chain with a moonstone pendant around her neck. Though, Capper had given her a Moon Opal pendant, in which she wears around her neck too.
But later on, her left ear was sliced during an ambush on Ponyville.
Personality:
Shira is super outgoing and jokes around a lot. She is also very calm, witty, sarcastic, kind, and brave. She sometimes jumps to conclusions through her observations. She is also incredibly loyal to her families and friends. She will do everything in her power to protect those in need, even if it means placing herself in harm's way. She is rather bold in her opinions and is quick to act. She seems to be a little prickly and very bold, and seems to hold grudges against those she dislikes.
She is an extremely independent, but optimistic cat who always attempts to see the best in others, even in past enemies (like Tempest Shadow). She also seems to be very forgiving of others when they do wrong. She is eager to find her place in the world and be accepted for who she feels she truly is. She is clever, creative, and a quick thinker, capable of coming up with solutions to problems on the fly, but if she has too much on her mind, she can be oblivious to things like, initially Capper's crush on her.
Shira usually plays amazing music, but plays best when she is alone by herself in a quiet spot. She has a philosophical side of hers. She is also a bit of a loner though over time she becomes more open and closely bonded to the rest of her friends. She also has a beautiful, lovely singing voice. Shira has a razor-sharp tongue and is very suave and skilled, which impresses Capper. She is the perfect mix of both of her parents. She's confident, street smart, and kind like her father and she's loving, sweet and beautiful like her mother.
Biology:
Shira was born to wealthy, unnamed parents who treated their daughter with great love and her older sister, Raine, loved her and protected her from their jealous stepsisters, Amber and Ivy Shadepool. The family resided in a stately château, just beyond a small — but powerful — trade kingdom.
She became a sleek aristocrat and a great singer, living the high-life with pride and dignity. That is, until Storm King came into power and attacked the city. After he had attacked the city, Shira was forced to travel a world to search for a new, but better life in the world. Lacking other means when she travels, she steals only to survive, but her good heart often moves her to donate her stolen goods to those who are as poor, if not poorer than her.
But during her travels, Shira had come across a friendly pegasus named Dawn Sky (my Oc) had taught her the spirit of generosity and taught her how to do art over the years. Thanks to Dawn Sky, Shira decided to bring the message of hope and peace throughout her travels.
