Born of the Silvershield Clan of Thelsamar, Tiergan was the youngest of five brothers. During much of his childhood, he learned the ways of mining as any good member of the clan, as he and his brothers assisted their father in gathering materials for the armors made for the militia. Eventually, he picked up the hammer and began to learn the craft of working those metals into the plate favored by the dwarves. He learned the craft at a quicker pace then his brothers, however, since he often gathered more metal than they did (given that he loved spending time in the mountains). He eventually came to crafting fine enough works that, when the First War struck, the Silvershield Clan helped with sending armors down to the Stormwind Army, while keeping the Militia's own armors in fine repair.
