Not every wolf has a glamorous backstory. Some are quite simple. And the beautiful Bear Nap is quite simple.
She was born into a litter of 2. It was just her, her brother, and her mother. Her mother, Poppy Kick, was a lone wolf who happened to hookup that mating season. Her brother, Sleepy Hound, and her were just like their mother... sleepy. Well, sleepy during the day. These guys were just insomniacs who stay up all night and sleep most of the day.
One day, she went off on her own, and so did her brother. They occasionally meet up, but just to chat and also cuddle while they sleep.
During the night, she studied herbs, and helped out sick or injured animals she met while she was awake. Soon, they all started coming to her. She didn't like it because they woke her up.
River Runner heard news of her, and asked to join. She joined, with only one condition - let her sleep.
You walk into the Herbalist's Den, and you see her curled up and snoring. YOu come back later, at night, and she is wide awake, organizing.
