Thanks xxRainStarxx for the first fact! {I found a few facts from @warriorcat_facts88 on Instagram}
***

-Tangleburr had a crush on Brokenstar when they were apprentices, but it faded when she realized how sour he was.

-Leafstar's biggest mistake as leader was chasing Sol away. It had a big chain reaction. She often regretted it just after he was gone, feeling as if something was wrong.

-Bluestar was the only she-cat ThunderClan leader.

-The Erin's killed off Stonefur so Mistyfoot could become leader.

-According to the family tree on warriorcats.com, Whitestorm fathered Ferncloud and Ashfur.
