Rodtranorn is from a rich, noble family from Erebor. His father owned  a mining business. He oftentimes accompanied his delivery dwarf to the great smithies of the Lonely Mountain. There, the workers often gifted small-Rodtranorn scrap and failed weapons and armor pieces. He quickly began to build his own armor and shield and played soldier.

Because of that, he was happy about being sent to the military while his older brother was to take over the family business. For his training he was sent to his family in the Blue Mountains. The husband of his aunt was a small landlord in the northern Ered Luin and was asked to train Rodtranorn. After that, instead of going home to Erebor again, he moved to the capital Thorin's Hall and joined the Blue Mountains Regiment where he found purpose, comrades and friends. During his years of serving, he saw leaders and officers come and go and is seen as a veteran despite his young age. He can often be met in the garrison and at drills, holding the line with his spear and shield.

He was considered missing in action somewhere in Rohan for some time but came back, nothing but a scar telling about his time lost. He doesn't like to talk about what happened.
