Arawn Midir, Chairn nan Niurin (“Lord of the Underworld”) is the immortal Lord of Niurin, and is a mighty Tuatha de Danaan. He has a great deal of power on the Isle of Man — second only to that of King Mannannan himself. Arawn is tall and slender, with black hair, white horns, pale skin and colorless eyes. Renowned for his courage and savagery, he leads the Wild Hunt across the island on certain nights (May Eve, All Hallows Eve), with a pack of his spectral hounds — white with red ears — and a train of other hunters. Arawn is the archetypal Unseelie,arrogant and unforgiving (he is also known as Arawn the Proud), but he is honourable, and does enjoy intelligent conversation; he also enjoys playing fichell (a chess-like board game), and is an exceptionally gifted harper.
He possesses a magical healing cauldron (Grui nan Niurin — the “spoils of Annwyn”), which will cure the wounds of the courageous, and is even rumored to be capable of restoring the dead to life.
He dresses in black armor, and rides a massive black horse, with red eyes, or rides a magnificent silverand- gold chariot, drawn by two of his black horses.
