Lillien

Lily That Blooms In Moonlight was never supposed to join the Pack of Chaos- nor was she ever supposed to be an herbalist.
But the newly leader-fied Aspen That Grows on Cliff had a moment of panic. Wolves in their (at the time) small pack were getting sick. And the herbalist was nested.
So they did what all leaders had to do. Find a wolf that she could tempt into the pack, and make that wolf the herbalist.
Lily was surprised. She found that she enjoyed the herbalist role, despite having no sort of natural ability for it.
As the pack grew larger, Lily's time started getting shorter and shorter. Then one fine day, a young pup was born.
This puppy was Feather of Golden Bird, a deaf female.
The pup's mother was horrified and didn't want to keep the pup. After all, she protested, she can't do anything.
"She could become an herbalist! My time is going to be up soon, and I need an apprentice." Lily, ever the stubborn one, kept the puppy in the pack.
Soon, Feather was all grown up. Lily gave her the herbalist role and padded away, now a mentor.
"I'm confused." Lily couldn't help but confide in her best friend Flamefur.
"I retired from my role, certain that Feather could handle it, but now I'm not sure. Nothing changed except the fact that I'm retired now."
Flamefur chuckled. Her fur, once a vivid orange color, was gray at the tips and her brown eyes seemed faded.
"We all pass on eventually, my dear. And that time is soon for me, so listen carefully.
It was different when you had control. Things are going to change rapidly now, so enjoy life while you still can. You need to persevere through whatever life throws at you, okay?"
Lily listened carefully and clung to the words, even after Flamefur passed.
After she passed.
After she had joined the wolves in the stars.
