Elbriech was born to a Rohirric woman and a Gondorian man, making him of mixed blood. He grew up in a modest homestead outside Dol Amroth , well-off due to his fathers occupation as a Sergeant in the Gondorian regiments. This also caused him to be away from home quite frequently. When home, he spent some of his time tutoring Elbriech on swordplay and fighting, using his military knowledge to make sure his son was able to defend himself.

Elbriech was never a fan of the grandeur of Gondor and its graceful arcitecture, and from the age of 7 called it, 'sillly', and, 'unnecessary'. This is probably why in future years he fit in so well with the Rohirrim.

At the age of 15, an abrupt change came to Elbriechs life: his father fell sick with a deadly virus, one that was incurable. He died shortly after contracting it, which caused his mother to decide it was best to travel back to Rohan. And so they did, back across Gondor, all the way to Kingstead, where Elbriechs uncle had a small farmstead. His uncle, though trying multiple times, had only daughters, and no wife to try for a son. So, after settling in, Elbriech began riding and mounted combat lessons with him, and soon became the son he never had. It was soon discovered that he was very proficient in these skills, and excelled rapidly. He was especially skilled with a two-handed battleaxe.

Elbriech soon mastered riding and fighting from horseback; he went from working on his uncles farm, to guarding Kingstead as a roving rider, helping where he could. Although he proved himself a Rohirrim several times over, he was never allowed the honor of guarding Edoras. This is how he spent many years, honing his skills, and protecting those who could not protect themselves. 

Once, when exploring a foriegn market in Edoras, Elbriech came upon a beautiful woman, whom he nearly instantly fell in love with. She shared his love, and it grew to be very intense, though was not to be allowed. Freya was already arranged to marry a wealthy lordling who had sizeable lands and riders to command. Here is where they broke apart, and here is also where Elbriech's motivation to leave The Mark begins.

Elbriech left home just after his twenty-sixth winter, the loss of his love, the poverty of his family, and wanderlust all playing a part in his decision. He went off, travelling everywhere and anywhere, selling his axe-arm where he could to make sparse coin. He seen many places, from the deep forests of Eryn Vorn, to the shimmering deserts of the Harad. He was alone, with just his thoughts to occupy him on most nights. It was a life not many could handle, yet he could not go back to his homeland quite yet.

Elbriech first came into contact with the Riders of the Riddermark on one visit to Bree. He came upon them, and realized they were Rohirrim. Better yet, an Éored. He joined the ranks immediately, and quickly grew to respect and enjoy the company of his own kin again. He set to fight under Rhinath in the Red Company, where his skills will be utilized to their fullest extent, spending much of his time here, until he was promoted to the rank of Haelwigend. 

Currently, Elbriech has forsook his position within the wandering Eoréd and taken up a post on the wall of Helm's Deep. No one quite knows why he has done so, but he dutifully fufills his position. Here is where he's destined to live out the remainder of his life, short or long as it may be.
