so, while ur a warrior, do u know the gray guy who plays moss ball in the warriors den while ur an apprentice? (his name is Darkclaw) well, when ur a warrior, he leaves the warrior den and does fireclan patrols. go to the warriors den and grab the moss ball on his nest. once ur done with that, u go talk to moonheart. when she asks smth, u say yes. after, u go to the fireclan border, and put the moss ball on the red X. Then, u wait for night and u sleep. the next morning, go back to the fireclan border and shell be there (if u slept on fireclan border go to herbal grounds and then come back) then u go to bramblestar and u can become leader when ur reputation points is at 80
