This is Sorreltail (she kind of looks like a dilute, but also not)
She is the daughter of the amazing Whitestorm and Willowpelt.
She had two brothers named Rainwhisker and Sootfur, also, Graystripe and Darkstripe might also be her brothers, but nothing about that has been confirmed in canon.
Her mate is the amazing Brackenfur, and together, they had six kits, five daughters, and only one son, who was an apprentice for about a week, before dying.
One of her daughters also died as an apprentice, because she tried to save a stick.
Another one of her daughters died because of a snake.
As for her other three daughters, they're still alive, and have families of their own, which consists of.... Hollytuft, Sorrelstripe, Fernsong, Honeyfur, Larksong, Leafshade, Molewhisker, and Cherryfall.
And some of THEM even have families, which consists of Bristlefrost, Flipclaw, Flamepaw, Finchpaw, Baypaw, and Myrtlepaw.
So, it looks like Sorreltail's family line isn't going to die out anytime soon
Anyway, enough about her family.
Sorreltail had a pretty hard life, she was poisoned as a kit, and almost died.
Then, she lost both her parents pretty much around the same time.
Then, her brothers died around the same time, as well as her son.
Then she lost two more kits.
Through it all though, she has been a strong cat who never turned to the dark side despite all the bad stuff that happened to her.
What are your thoughts on her?
