These are only the leaders mentioned in the books.
Thunder(star), Owlstar, Pinestar, Sunstar, Bluestar, Firestar
Wind(star), Heatherstar, Tallstar, Onestar
River(star), Hailstar, Crookedstar, Leopardstar, Mistystar
Shadow(star), Brightstar, Flowerstar, Cedarstar, Raggedstar, Brokenstar, Nightpelt, Tigerstar, Blackstar
Skystar, Cloudstar, Leafstar
I know that these are only a few of the leaders, but these are the one merely mentioned IN THE BOOKS so please don't get angry that I didn't mention every single one, this is my first blog and I didn't know what it should be about so this is why this isn't exactly perfect. But if you leave a comment telling me what leader I did not put, I will add them to this small list.
