There is one cat in the Warriors universe that has caused, directly or indirectly, almost all of the horrific things in the Warriors series that have happened so far. One cat. That cat could be described as not exactly evil, but if you looked into the cat's heart, you would see darkness. Darkness that acts surprisingly well with the stupidity and recklessness in the cat's mind. This darkness has passed onto other hosts, and has multiplied throughout the clans. Fear and sorrow has sprung from the forest and lake areas, and the darkness thrives. Normal darkness, like that in Brokenstar, dies out with the cat who was it's host, only affecting a few cats who are alive in the lifetime of the host. The darkness in this cat, however, spreads like wildfire in a dehydrated forest; dangerous and deadly. One cat started it, and that cat is Thistleclaw.

Thistleclaw has caused so many things, affecting many cats. It's surprising that a cat of Thunderclan would carry the rare type of darkness. "Why not Shadowclan?", you would ask. That question cannot be answered by me, as hard as I try to. Fate is a strange thing, indeed. It chose Thistleclaw, so we have to accept that and move on. Here is a list of important cats Thistleclaw has either infected with darkness, or has caused indirect or direct pain or death in their lives:

1. Bluestar (directly and indirectly)

2. Snowfur (directly)

3. Tigerstar (infected)

4. Sasha (indirectly, through Tigerstar)

5. Hawkfrost (indirectly, through Tigerstar- infected)

6. Mothwing (indirectly, through Tigerstar)

7. All cats Tigerstar has killed (indirectly, through Tigerstar)

8. Scourge ( infected)

9. All cats Scourge killed (indirectly)

10. Brambleclaw and Tawnypelt (indirectly, through Tigerstar)

11. Ashfur (infected, through Hawkfrost and Brambleclaw)

12. Firestar (indirectly, through Tigerstar mostly, and Scourge)

13. Cats of all clans in war caused by Tigerstar and Scourge

14. Mistyfoot and Stonefur (indirectly, through Tigerstar and Blackstar)

15. Hollyleaf, Jayfeather, and Lionblaze (indirectly, through Ashfur)

16. Blackstar (slightly infected, through Tigerstar)

17. Ravenpaw (indirectly, through Tigerstar)

Those are all of the cats I can think of at the moment, but there are probably more. As you can see, most cats are indirectly caused pain or death through Tigerstar. It is to be expected, though. Tigerstar was Thistleclaw's apprentice, and Thistleclaw was practically Tigerstar's father, since Pinestar abandoned Thunderclan for Twoleg life. Thistleclaw taught Tigerstar basically all he knew, and it was apparently a lot. Thistleclaw's personality and prejudices were passed onto Tigerstar.

I would like to raise the question of what would happen if Thistleclaw was born without the darkness in his heart. My answer, a lot of things. The warriors series would have to be re-written. That is this fanfiction's purpose is. To tell the story of a world with a good-hearted Thistleclaw.

A/N: My first fic!! YAY!!! Sorry if I offended Thistleclaw lovers(if there are any). I was ranting with my friend, Froststar423, about how much I hated Thistleclaw one day. Suddenly, we started listing of things that would change in the Warriors series if he were to be good. We came up with a LOT of things that would happen different. Unfortunately, Brokenstar turning good was not one of them. It may take me a while to get up the next chapter, maybe a month or two (I have school and a tiny social life to keep up with), but I promise that updates will pick up in the summer. I will never give up on this fic though. I start a fic, it is guaranteed that I will finish it one day, even if it takes me several years. Bluestar's Prophecy is a must-read for this fic, since it will pick up on the day of Thistleclaw's apprentice ceremony, or somewhere around that time. Reviews or constructive criticism are accepted, but flames will be shunned. Hope you enjoyed! :D

Edit: I have taken out the theory part related to Scourge, thanks to you wonderful reviewers who have confirmed my theory. I haven't read the manga, but maybe I'll be able to borrow it from somebody. Thanks! :)
