Galtheon was born in a village close to the borders of Rohan; he lived on a small, yet comfortable homestead with his mother and younger sister, and at the age of thirteen began to work as an apprentice to the local blacksmith. At this young age, Galtheon's duties mainly included running errands and delivering orders to customers; but at fifteen years old, his mentor finally saw fit to permit him use of the forge for the first time.

Galtheon trained hard under his mentor, learning all that he could about his chosen trade. He soon became skilled enough to earn the trust and respect of both his mentor and the rest of the village; he saved what money he could to give to his mother, and thus he spent his teenage years in comfortable peace.

When Galtheon turned twenty-four, his sister accepted the marriage proposal of a young landowner from Edoras. When she went away to live with her new husband, he welcomed his new bride's mother also to join them; and so they left for Edoras, leaving the family home to Galtheon.

Galtheon lived alone for a few months, before growing weary of things. He had spent his childhood working hard and so had seen little in the way of adventure or travel; he decided then, that now he had his freedom so to speak, he would set out into the world and make up for the adventures he had missed as a child. He sold the family home and sent two thirds of the proceeds to his mother, using the other third to buy a horse and provisions for his journey.
