Born in Hverfgardr in the Eretejva Tundra, Tyrfingr had the same kind of childhood as all members of his clan. He began learning how to craft the moment his tiny hands could grip materials and tools. Training was made up every part of his life. Smithing, tailoring, leatherworking. No craft was left unlearned. Hunting, foraging, runecraft as well. Anything that could support his crafting.

After Tyrfingr reached adolescence he had a strange dream one night. He dreamt he had fallen into a river and it froze over, leaving only his head free. The teen Tyr struggled to break out. He failed. His parents heard the terror he was going through in his sleep. When they rushed into his room they found his fur blanket had turned to stone. Once they freed him of it he was taken to the clan shamans. They confirmed his gift of magic had awakened. A new area of training was added from then on.

The Rynstr clan's rite of passage into adulthood is a test of their skills. They must create a new work from materials they gathered themselves. They recycle old, flawed works. Hunt, forage, and grow what they can not recycle. All must go through this to provide a work of sufficient skill and use. Tyrfingr being gifted with magic needed to make an item even more so.

After months of work what Tyrfingr presented to the master crafters of his clan was a twisting tree root inlaid all along its length with various metals. Iron, copper, tin. All of them were held into place by rings and a pommel made of boar tusk. What he had given them was a tool. A tool that magically lead wielders to deposits of these metals. As wild boars and the roots of trees seeks out minerals to live, so too does the rod. The inlays softly glow to indicate which metals it has found and the root tug at the wielders hand towards near by deposits. This impressed his clan members and earned him the body tattoos that identified him as an adult. They shaped them to look as roots and ore veins to represent what earned him his place.

Tyrfingr did not remain idle in his adulthood. The praise he had received for his writ of passage lit a flame inside of him. A thirst for glory he had not known before was born. He continued to perfect his craft. Newer, rarer, and more exotic materials were needed for each new work. His hunger for glory and perfection drove him to hunting an unusually large bear. This bear had ended the life of many hunters and it nearly killed him as well. He had found the beast and threw a spear into it. Angered the beast charged faster than the norseman expected. He barely had time to raise his second spear up to impale it before it could sink its fangs into his throat. His reward for its death was the glory of the kill, its wonderful parts for his crafting, and a swipe across his thighs that would have crippled him if it was slightly deeper.

This was the first humbling event Tyrfingr had faced. The wound the mighty bear left Tyrfingr with at its final moment would have killed him as well from blood lose. If not for his cousins being nearby felling an oak tree for a project of their own hearing the roar of the bear he would not have survived. For the first time Tyrfingr realized the cost one must pay for perfection. He gave his cousins everything from the bear but its pelt and blood. A great feast was held by his family and their friends. He turned the pelt using the blood into a cloak that allows him to assume the bears form.

The second humbiling event Tyrfingr faced was when he spent months working on an ambitious project. A shed that stayed the perfect temperature for storing food at all times. He found the right trees. The right stones. The right mud. He fused each piece with magic as he put it all together. But he made a mistake. While placing the final piece that would have completed his project his mind trailed to how glorious it would be and he lost his concentration. His transmutation magic failed and everything he had worked so hard on crumbled to dust. The backlash left him bedridden for weeks. Weeks he spent cursing his failure.

Tyrfingr went back to improving his skill with magic. But after a couple of years his third humbling came. He became too obsessed with making up for his failure and began a new project. He wished to make a dagger that could become any weapon or tool the wielder needed. He became obsessed with it. Nothing was too rare or difficult to obtain for him. He didn't know how long it took him but eventually he had gotten everything he needed. He just lacked one final material to complete it. Luck was with him as an old sword contained what he needed. So in his clan's tradition he recycled the sword. He finished up his tool, but it did not come out as expected. It did indeed shift its shape but it couldn't turn into anything that wasn't some kind of blade.

While there was some praise for his tool despite its flaw, Tyrfingr soon came to be shamed. One of the elder master craftsman recognized the part he had recycled. The old sword was a masterwork of one of the clan's greatest swordsmiths. Recycling is a part of his clan's tradition but a masterwork is never to be recycled. It is even worse if it is used to make an inferior work.

Tyrfingr had committed a taboo for his clan. This devastated him. Worse was that his clan chieftain under the advice of their elders banished him from Hverfgardr. He can only return when he has crafted a masterwork to replace the one he had taken from them.
