During his short life his people lived in the Grey Mountains, where they were threatened by and at war with Dragons. In 2589 both Frór and his father were killed by a great Cold-drake outside their halls.
Frór's older brother Thrór then became King of Durin's Folk and led part of his house back to Lonely Mountain. The rest of those who left traveled East to the Iron Hills with the youngest brother Grór, who founded his own realm.
