Lillie:

With Lillie being raised in a cave by a bunch of poor people, her fear of caves became nonexistent when she first heard of Cave Diving. Heck, she became obsessed with it as she got older. Completely aware of the fact that she could die from it, she wasn't afraid and was really happy-

Until one day she fell into a deep cave killing her when she hit the ground :3

Wolfie:

She was very unsure of Lillies weird obsession with Cave Diving, though she had grown to like it a little, considering the fact that she had only heard the good side of it. Though at a young age, she ended up dying to a terrible disease. It had seemed like she had never given up though, since she would spend time with Lillie as a ghost until she eventually had to let her go.

Wolfie and Lillie are twin sisters, even though they almost look nothing alike. It was unusual for Lillie to be born as a cat in a family of wolves, though she was still treated with care.

The two were friends with other characters like Ginger, Emily, and another character I probably NEVER mentioned.. Isabel.

There are a couple other AUs of them though, that I probably won't get into because they would probably take up a whole 3/4ths of this article.

Wolfie and Lillie though are some of the favorite characters that I've made, and I like them a lot more after I have made up a decent story for the two
