Shielding Middle-Earth.
Throrghar comes from the Iron Hills, where King Dáin Ironfoot II made his refuge when he had to flee from the cold drakes in the north. Throrghar was born there in T.A. 2929, so he is considered rather young for a Dwarf.
When Thorin Oakenshield called for aid to defend the Lonely Mountain after the Dragon Smaug had been shot by Bard the Bowman of Laketown, King Dáin rallied most of his army and marched quickly West to Erebor and the Lonely Mountain. Throrghar, being too young and yet unskilled, did not go with them.
Dáin fought together with the Woodelves of Mirkwood, and also the Beornings and Eagles, against the Goblin army that came from the North to claim the Dwarven treasures within the Mountain. After the Battle of the Five Armies in T.A. 2941 was won, King Dáin became both Lord of the Iron Hills and now also King under the Mountain and therefore moved to the Lonely Mountain to re-establish the Dwarven Realm. Thorin, the heir to the throne, died shortly after the War from his wounds he sustained while trying to slay the Great Goblin, in which he failed. When he was severely wounded and lying on the ground the skinchanger Beorn came onto the battlefield as a great, mighty black bear and hewed down the Goblin guards, saving Thorin and he took him back to safety. Then Beorn returned in anger and rage and eventually slaying the Goblin Chief, Bolg, in revenge.
Throrghar admired the great craftsmanship of armour that was found in the Lonely Mountain, so there he started training how to use a shield and armour in combat to his advantage, like his father. It was he who gave Throrghar the name Broadshield; when he was young he always wanted to carry his fathers' great heavy shield, but being still a small Dwarf Throrghar had to carry it with the broad side up.
Also he started to learn the craft of making armour, but he had to stop his training in T.A. 2990 as he was sent away with a company of Dwarves to Khazad-Dûm, to gather news and help to establish their Realm there, for Balin had set out on expedition a few years earlier to re-colonise Moria, although King Dain wasn’t too fond of that.
When Throrghar reached Moria he was fascinated about Mithril, the most valuable and important source to make the very best armour ever, but that lore is now gone. However, is was very difficult to establish their new Realm in Moria with many foul creatures such as Goblins lurking close by, so in T.A. 2993 Balin sent him away to Thorin’s Hall in the Blue Mountains, at the shores of the Western Sea, to call for aid.
When Throrghar reached the Blue Mountains, he found works of the enemy present there also. Dwalin, the leader, asked for his aid to investigate the doing of the Goblins nearby, before they could march to Moria. Then the treachery of the Dourhands clan was laid bare and Throrghar helped Dwalin to solve the problems with force, claiming back the stolen treasure. However that almost claimed his life on one occasion, but for him wearing a helmet.
Then more problems had to be solved, so Throrghar did not return to Moria (yet) and knows not Balin and his kindred are slain and the Halls and stairs of Moria deserted but for Goblins, who attacked Moria in T.A. 2994, one year after Throrghar left, overpowering the Dwarven colony. Thus Throrghar still resides in the lands about Thorin’s Hall, defending the Hall of Dwalin, but hoping to get back to Khazad-Dûm soon.
