He was born and raised in Rivendell by Menaladar and Nanneth. He was always adventurous, and known as a cohort of the mischievous Elladan and Elrohir. After they had all grown, the three went to the Misty Mountains to hunt goblins. They decided to visit Lothlorien because Arwen was there. Just outside the Lorien border they were attacked by orcs. Then an elf jumped down from a tree, and Dirion reflexively shot him. The elf was only injured, so they took him to receive treatment. Unfortunately, Dirion had good aim and the elf died. Of course, when one elf kills another elf it’s pretty much unforgivable, so Dirion ran away. Elladan and Elrohir tried to track him for a while, but they eventually lost him. Dirion just wandered for a while until he decided to disguise himself as a human. He then wandered into a smal village in Rohan where a family clothed and fed him. They called him Arfaestgod. He worked for them for a few years, until he had enough money to buy a horse and a sword. Then he left and did a few paid jobs while wandering around Middle-earth. He went to the South for a while to see the tribes down there, and he got a knife from them. He still avoids the West of Middle-earth and elves, but sometimes wanders in to see his friends and kin (without revealing his identity of course). He also visits the family in Rohan often.
