Rolphar Storm is an unseen character in Game of Thrones. He is one of the many bastard children of Lord Jothos Harrigon. He is a chief blacksmith at Smithestone. He is good friends with Smithestone's master-at-arms Ardrew Ashes.
Rolphar is the son of Jothos Harrigon by the unnamed daughter of a farmer who lived near Smithestone. Jorthos immediately brought the infant Rolphar and his mother to Hornworth, where he was raised outside the walls of Hornworth until he was 10 years old. From there he was trained as a blacksmith inside Hornworth's forges.
Rolphar has been a loyal member of house Harrigon and all of his half-siblings, even helping to train a young Rickard.
