Congrats to sukistorm for guessing the last cat! It was Hawkfrost! Here's the next one...

Born in shadow,
Dressed in black,
Littermates,
Broad face,
Felt others pain,
Sadly to say,
Had to train,
The medicine way,
Fell in love,
Against the code,
Sadly to say,
Kits did came,
Two died,
One survived,
Hatred in eyes,
Chased out by son,
Found by the one,
Felt like her son,
Adopted clan,
Killed by flames,
Starclan welcomed.

Who am I?
