Cinderpelt (formerly)
Brackenfur (temporally)
Cloudtail
Bramblestar
Bluestar's first apprentice was Frostfur. She later mentored Runningwind and Firestar.
Well as much as a read he only had two Cinderpaw and Cloudpaw. I'm not sure if he has anymore. Anyway Cinderpaw becomes Cinderpelt, and Cloudpaw I think he becomes Cloudpelt or Cloudfur.
Yes but only temporarily. She later then became Sharpclaw's apprentice in Firestar's Quest. Its not the Cherrykit in Thunderclan who people might think will become Cherrytail and Firestar's apprentice but the kittypet who joins Skyclan who is know as Cherrytail in Skyclan's Destiny. Her brother is Sparrowpelt who was know as Boris as a kittypet.
Graystripe is about the same age as Firestar. He is about 65 (in human age). They became apprentices at about the same time.Roughly eight years old as of The Forgotten Warrior.
There are apparently three cats on the front cover: Hollypaw, Lionpaw, and Jaypaw. Behind them is an image of lightning in a forest. Firestar's three grandchildren must become apprentices, ( Names are shown above ) which one will they choose? And why?
Firestar
They might be since Firestar's daughter, Squirrelflight, is Brambleclaw's mate.
It is unknown if she has mentored any apprentices.
He offered Firestar to sleep in his backyard for one night.
No . Firestar's kits are Leafkit/paw/pool, and Squirrelkit/paw/flight. Graystripe is Firestar's best friend and Silverstream was his mate.
this is an opinion to me it would be Firestar
Fireheart's apprentices were Cinderpelt, Cloudtail, and Brambleclaw.
