Glaurung was the first of the ancient dragons bred by Dark Lord Morgoth. Most scholars and keepers of the old texts know that this treacherous walking evil (known also as "The Worm of Morgoth" or "The Deceiver") was slain by Túrin Turambar. But not many know that the dragon already nearly breathed for the last time many years before that, by the hand of dwarven king Azaghâl of Belegost. Azaghâl led the dwarves of Ered Luin into the Battle of the Unnumbered Tears and was slain by Glaurung. In his last moments, Azaghâl managed to strike the worm into his belly and made him flee along with his army.

This is how and when dwarves of Ered Luin obtained a few Glaurung's scales as trophies, which they carefully preserved ever since as the memory of their King dying honourably facing the terrible beast. Armour with just one of these scales has unspeakable value. Gerbag, the brave guardian of Whitywindle, has proven worthy of wearing it for his deeds against the Dark Forces, slaying the mighty Draigoch being just one of many.
Gerbag is already a stable contributor of this blog and I am so grateful for him, as he truly has an eye for distinguishable dwarven outfits. I am jealous of the wonderful helmet which I've never seen before and Gerbag also admits he wears it because it's very rare and not anyone can get their hands on it.
However, he was kind to provide an alternative which also works well for this outfit and is much more easily acquirable.
