Fallenangel

Fallenangel
TwilightClan
Night black she cats with very, very, very, very green eyes. Her eyes are also slightly startling if it's the first time you see them.
Fallenangel was a former medicine cat, who had been medicine cat for many, many moons and trained the current medicine cat ______ (insert the name of my TwilightClan medicine cat here).
She was very friendly, and humorous, and loved to crack jokes. Nice and caring, every cat in the clan respected her. After an accident nearly killed her and killed her parents, her best friend, Lilyshadow, and her apprentice, Birchpaw, she's doesn't trust cats easily, because the accident happened when one cat did one action wrong, and has a very, very, sharp tongue. If you're very lucky, and catch her on a very good day, you can still see traces of the old Fallenangel.
She's clanborn through and through, though she doesn't care about stuff like that.

How could she be a medicine cat for a long time, when Twilightclan hasn't been around all that long?

Otherwise, I like her description. What was the accident?

Just those 2 things and it is approved.

Um, for as long as Twilight has been around? YEAH!

Uh...
AH HAH!
Tragic accident time.

It was a very stormy day. Fallenangel was out gathering herbs with Birchpaw, and she tagged along a patrol lead by (random warrior) Stemcrackle, and that consisted of her parents and her best friend. They smelled fox and badger on the place where Fallenangel usually gathered herbs. They were about to attack and drive the bad animals away, when Stemcrackle stepped on a stem that was unusually sharp, cracked it, (LOL), yowled with pain, and alerted the fox and badger. They attacked the cats, while a tree fell down and killed everyone. Only Fallenangel survived. She actually blames herself for that accident, if she didn't go collect herbs that day and didn't go with that patrol, everyone would be fine. As soon as she got back to camp she resigned as a medicine cat.
