*Spoilers for Bluestar’s Prophecy*
This question was asked for Warriors Wednesday by Corrie.S.P.
Pinestar gives Bluestar a life for compassion,
Mumblefoot gives her a life for endurance,
Larksing gives her a life for humour,
Sweetpaw gives her a life for hope,
Sunstar gives her a life for courage,
Goosefeather gives her a life for patience,
Mosskit gives her a life for trust,
Moonflower gives her a life for love
and Snowfur gives her a life for pride.
Here was something I found from the Warriors Wiki:
One clear mew, ringing with every voice Bluefur had ever known and loved, welcomes her. Pinestar steps forward first, touching his nose to hers. He gives her a life for compassion, causing Bluefur’s pelt to feel like it’s being scorched by frost and flame. Next, Mumblefoot steps forward, giving her a life for endurance, causing her to have to endure a sudden wave of pain. Larksong gives her a life for humor, and it makes Bluefur’s pelt stand on end. A cat who the blue-gray she-cat hadn’t noticed at first steps forward, and she recognizes Sweetpaw. The small cat stretches up to Bluefur’s head and gives her a life for hope, causing the new leader to feel like she’s running in a forest, a bright light shining through the trees. Sunstar takes the apprentice’s place, and gives her a life for courage. Their gazes lock together, and her former leader’s eyes are filled with warmth and gratitude. Goosefeather is up next, giving Bluefur a life for patience, adding that she’ll need it. Peace floods through her, and she feels ready to embrace anything in its turn. Bluefur momentarily wonders if Goosefeather had known that everything would turn out the way it did. Mosskit steps forward to give her a seventh life, a life for trust. The small kit’s mother finds her voice, apologizing. The kit says that she understands, but she misses Bluefur. Moonflower steps forward to give her an eighth life, one for love. The blue-gray she-cat feels as though she’s being crushed by the Moonstone, feeling suffocated until light suddenly bursts from her heart. Bluefur knows who the ninth life will come from, and Snowfur steps forward. The white she-cat gives her sister a life for pride, and for a moment the new leader is convinced she is on fire.
That’s as much as I could find. If you want to know more, I would suggest reading the book, it only has slight spoilers for the first series.
