Tigerstar kills him in the dark forest vs starclan battle in the omen of the stars last book
I think Firestar dies in the big battle agianst StarClan and the Dark Forest..
Firestar joins StarClan after his death in battle. StarClan is where the spirits of all good cats go after they die, and Firestar shows his loyalty and devotion to his Clan throughout his life, earning his place among the noble ancestors.
It is not confirmed when, but it will happen in Omen of the Stars
Firestar escorted Bluestar to StarClan when she passed away. He was a close friend and former deputy of Bluestar, and he guided her to join the ranks of the ancestors in StarClan.
Firestar made Brambleclaw deputy because Leafpool had a sign from StarClan saying he was the right choice.
Firestar was the main point of StarClan's prophecy, Fire alone can save our clan. He helped drive out BloodClan from the forest.
After she died, Bluestar joined starclan.
Whitestorm was a senior warrior, meaning he had lots of experience. He was a supporter of Firestar when Firestar was deputy, and he had an unshakable faith in Starclan. When he was appointed deputy, Firestar commented that Whitestorm's surprise at getting the position was part of why he was chosen.
Firestar loses his last life in the last book of Omen of the Stars, or so I've been told. Erin Hunter has said that she doesn't know how she is going to make Firestar's death.
yes and that makes sandstorm angry
At the beginning of the Series, Firestar will be leader. If Firestar does join Starclan in this series, it does seem likely that Brambleclaw will succeed him as leader. Some other possibilities include:LionblazeGraystripe
In StarClan, Firestar would likely love both Spottedleaf and Sandstorm as they were important cats in his life. However, his love for Sandstorm was stronger as she was his mate and they had a family together.
