Graham shares his food with an eagle
.Eagles are large birds of prey, with very large powerful hooked beaks and an extremely keen eyesight.
After walking down the mountain path in Llewdor, Gwydion sees an eagle flying around. It drops a feather near Gwydion, and he uses that feather to cast "Flying like an eagle/fly" spell. Then he can become an eagle each time he dips the feather into rose essence.
King Graham meets an eagle dieing from hunger in Icebella's Realm, and gives him his last bit of leg of lamb. Later the eagle saves Graham's life from the Roc's nest in gratitude.
