Arawn is from the Welsh branch of the Celtic Pantheon. He's the God of death, war, terror and revenge. He was the king of the Otherworld realm called Annwn, which is said to be a world of delights and everlasting youth where disease and illness doesn't exist and the most delicious foods are abounding. He's the Keeper of Lost Souls and is known to be riding his beautiful horse, with his white and red eared hound dogs running right beside him, through the Autumn, Winter and early Spring skies. Some say they are hunting for wandering spirits, while others saying they are hunting the Fey. He was also one of the gods of the Tuatha de Danaan (a group of powerful Deities led by the Goddess Danu). Arawn's name at birth was Donn mac Midhir to Mider
