Lilac

Lilac was a wolf born in Bloodpuddle's era. She had a crush on Bloodpuddle and was hurt when he became mates with Hazel where she hadn't even professed her love to him.
Later, Hazel would go missing, and be found dead, obviously murdered. Lilac, seeing an opening and taking her chance, convinced Bloodpuddle to meet up with her at sunset, where she professed her love.
Bloodpuddle was not interested, but Lilac was desperate. She kept pushing her luck, until Bloodpuddle threatend to kill Lilac if she didn't shut up. He startled her to stumble backwards, falling off the cliff to her death.
Fern somehow messed with Starpelt's script, and made the Spirits not realize that Lilac had died and needed to be transported to the Stars, and Lilac was left forgotten on Renta, as a ghost.
Lilac spent nearly a century wandering from one life to another She grew to regret what she had done when she was alive, and despretatly wanted to join the Stars. Lilac believed that this was the Spirit's way of punshing her.
When Bloodpuddle was revived, Lilac decided to spy on him, in attempt to gather information and complete what she thought was her purpose. During the Battle of Blood Moon, Lilac saw Moonmist struggling to fight Bloodpuddle. Lilac stepped in, using her willpower to be visible for a couple moments, and distracted Bloodpuddle long enough for Moonmist to regain a bit of strength and kill him.
Lilac met Blue outside of the Night Barn, when he was trying to save his sister. Blue was the only animal who could see Lilac without her needing to reveal herself. Lilac grew attached to Blue, as the only animal who she could talk to, although she didn't approve of what he was doing, and would constantly try to convince him to stop working with Ember.
One night, before Ember planned to burn the forest down, Lilac visited the Night Barn and met Nightshadow. Nightshadow was able to see her for a little bit because of the night being able to heighten her senses, and Night feeling calm. Lilac and Nightshadow spoke, and Nightshadow was the first animal in over a century to ask Lilac what her name was.
After the fire the put the sun out, Blue was guilty about the death of Nightshadow. Lilac tried to talk to him but was intrupted by Ember, who stood in Lilac, revealing that she was a ghost.
Once Blue came to terms with the fact that Lilac is a ghost, the two decided to work together and help Duststorm fight Scorpion by being spies.
When Bloodpuddle came back to drag Fern into the Stars, he spoke to Lilac, saying: "I know you're here, watching still, thanks to the Spirits being blind and not doing their job right." which made the Spirits realize that Lilac had been on Renta for over a century.
Starpelt went down to Renta to bring Lilac back to the Stars herself, not before Lilac saying good-bye to her best friend, Blue.

Lilac is attracted to male wolves. She had a crush on Bloodpuddle.

Lilac knows how to read and watched a handful of human classes as a ghost.

Lilac helped Moonmist defeat Bloodpuddle by distracting him long enough for her to regain her strength.

Lilac died and didn't go the Stars.

After spending a century observing the animals on Renta, Lilac fiercely believes in second chances, if they are deserving.

Lilac constantly wondered why she was cursed to wander Renta as a ghost. At first she thought that it was a form of punishment by the Spirits, since she murered Hazel. But then Lilac realized that there were no other ghosts around, and there certaintly animals who killed for other reasons, as terrible as hers.
Lilac began to wonder whether she could rest without something, such as closure, an item, or a friend. But Lilac never felt like she desprately needed something.
Lilac then thought that she needed to learn a lesson, but once she finally realized that what she done in the past were wrong, and that she wanted to apologize to Hazel, she still wasn't able to join the Stars.
Finally, Lilac decided that there was purpose as to why she was stuck on Renta. At first, she thought it was helping Moonmist defeat Bloodpuddle, but to her disppointment she still remained a ghost, and almost lost complete faith in the Spirits, until she met Blue, who she was certain was her purpose to help.

The story surrounding Lilac's death became a favourite in the Night Barn. Lilac hated that her story was close to the truth and yet still inaccurate. She hated how whenever she visited to the Night Barn, she was forced to listen to her past mistakes, and how no one bothered to remember her name.
After Lilac's conversation with Nightshadow, Night changed the story to be more accurate, and always made sure to tell other's of Lilac name.

Lilac slowly began to lose faith in the Spirits when she didn't join the Stars.
