Echoflight, Sunfire and Firestorm are the last kits of Firestar and Sandstorm before the latter's death in the Battle with the Dark Forest.
Echoflight is a gray tabby she-cat with brilliant green eyes.
Echoflight was born moons after the great battle with the Dark Forest to Sandstorm and is the sister to Sunfire and Firestorm. Her father, Firestar, died from the great battle.
Echoflight was last to be born thus making her the youngest. Echoflight was constantly in the medicine cat den learning about herbs from Jayfather. Whenever she was with Jayfeather and Briarlight, Echoflight could sense Mille staring at her.
Echoflight was worried that when reaches her sixth moon and might be taken on as Jayfeather's apprentice, Millie will get mad. But Briarlight reassured her that it's OK for her to be Jayfeather's apprentice. She tells her that they both can help Jayfeather and when one is not around the other can help. Since they, Echoflight has become very close to Briarlight and makes sure Briarlight is OK.
