Born roughly ten years after Erebor was retaken, little Thunaraz was enamored with tales of Thorin Oakenshield and Co., resolving to be less greedy. Aging, he took his father’s(Thârkun) craft, seeing the glittering armors which sometimes made their way into their home. Or when he played with his friends in the halls, he tried to guess which plates his father crafted and which suits were of his friend’s parents make. He became apprenticed as young as his father would let him, helping around the forge, and seeking to improve his craft. Soon Thârkun taught him the different ores and how to shape each. Once he had well learned, his craft improved, and he was sufficiently behaved that week. His father would take him down into the mines, soon they were mining oars together, loading and unloading carts.

‘Til one day tragedy struck, Thârkun was drinking with his friends celebrating a grand hall, while Thunaraz was getting ready to shut down the forge for the day. Cave-Crawlers bored into their family hall, spewing out from paintings and furniture. Overrunning Thunaraz’s mother. By the time he got back from locking up the forge, he came home to his mother half-eaten on the floor. His father’s hall, a nest for vermin. With his smithing hammer, he felled most of the creatures, but some fell back into their tunnels as their brood died around them. Thunaraz waited there, his mother’s corpse and terrified eye in his arms. When his father stumbled in, there were few words between them but many blows. 

The rest of his youth went much like that, Thârkun becoming more and more of a drunk, while Thunaraz picked up more of the business. Each night they would fight, sometimes his father would win, but as time passed more and more the son was the victor. Thunaraz's armor make also improved greatly during that time, and he began to train in arms with some friends in Erebor. More and more King Dain sent for him, instead of his father to lead repair efforts or to help clean out sections of the mountain.

Now an adult but still young by the years of Longbeards, Thunaraz has an intense dislike for his father, even the mere mention of him can put the dwarf in a sour mood. Yet, as Erebor was finally restored to its glory before Smaug. He set out for a boar in the Iron Hills, so that he might see other halls and band together with other Dwarrows to retake them. On his return to the Lonely Mountain, his father stood waiting, with a finely crafted armor set for his boar. Thunaraz took his father’s gift but did not give in forgiveness in return. He journeyed west that day, with a hard heart, and unwavering hatred for all enemies of Dwarves.

Currently, he ventures to the Blue Mountains from his forge in Erebor; when not serving the kin of Durin's Folk.
