Sunkit was born to her mother, Yarrowfeather and her father, Acorntree. She had a sister named Moonkit. She had a normal kithood, playing with her sister and getting into trouble. She was a very different cat back then. She loved to run and play mossball, and she was really close with Moonkit. The two of them were inseperable. Even though there was a war going on, the two kits never seemed to bat an eye at it.

As she got a little older, Sunkit noticed Yarrowfeather would leave the nursery a lot to go out on patrol, but she thought nothing of it. Acorntree went too. It wasn't until later that Sunkit realized they were helping to patrol the border, due to the war going on with the StoneRaisers, and the Clan needed all the help they could get.

This continued for the rest of her kithood. Her parents would leave her behind, and sometimes Sunkit and Moonkit would be forced to hide in the nursery because an attack on the camp seemed likely. Sunkit was beginning to realize the reality of her life.

Sunkit finally became an apprentice: Sunpaw, beside her sister, Moonpaw. Sunpaw was given a strict mentor named Sharkfang, who was meant to train her hard and fast so she would be prepared for anything should the worst come to her. Sunpaw, however, was a dedicated apprentice, and always tried her best.

Sunpaw and Moonpaw trained together with their mentors most of the time, now becoming more serious as to what was really going in within their borders. Sunpaw hated the harsh training, but knew that she had to train hard in order to be the best warrior she could be, and protect her Clan.

Towards the end of her apprenticeship, there was a battle. Sunpaw faught hard alongside Moonpaw, Yarrowfeather, and Acorntree. At the end, Yarrowfeather, Acorntree, and Moonpaw were murdered, leaving Sunpaw as the last remaining family member. She was devastated. Her mentor, Sharkfang, was also killed.

Shortly after the battle, the leader recognized Sunpaw's skills in battle, and named her Sunbeam for her determination. Sunbeam wore her name with pride, vowing revenge for her family's deaths.

As a new warrior, Sunbeam sat vigil in the camp, keeping a close eye on the entrance, standing at the ready. She was angry, and she was determined. How could she have let this happen? She couldn't protect them, and she should have.

Soon later, the Clans declared peace with each other, and Sunbeam was forced to stand down from her vengence, but the image of her dead family will always be sketched into her mind, and she cannot forgive.
