Lilith

Lilith is a non-playable character from Fire Emblem Fates. She is an Astral Dragon that lives in a Shrine in My Castle.

Profile
Lilith is the Avatar's attendant, and always follows them when she can. She can help her allies when they fight in My Castle during StreetPass Battles and Castle Invasions. Lilith will accept any food made in the Canteen. As she is fed, the food given will affect her stat growths. Interestingly, she is capable of using staves and breath weapons, such as her Astral Breath. She will also give the Avatar a Gold Bar every three levels she gains.

Lilith first appears in Chapter 1, where she sees the Avatar off when they leave the castle. Later in Chapter 3, after the Ganglari throws the Avatar into the chasm, Lilith suddenly appears and transforms into her dragon form and rescues them by transporting them into the Astral Plane. It is here that she reveals that they first met when the Avatar was very young. The tiny baby bird that they found and nursed was Lilith. Grateful for their kindness, Lilith wanted to be by them for the rest of her life.
