“What did he promise you? A share of the treasure? As if it was his to give. I will not part with a single coin. Not one piece of it. My teeth are swords! My claws are spears! My wings are a hurricane!”
“The Dwarven language was created by Aulë, and was called Khuzdul. It was a strange language to Elves and Men, and few non-Dwarves learned it, because it was difficult, and the Dwarves kept it secret, preferring to communicate in the languages of their neighbors. Only one Khuzdul phrase was well known to outsiders: the ancient battle cry, going back to at least the First Age: “Baruk Khazâd! Khazâd ai-mênu!”, which means “Axes of the Dwarves! The Dwarves are upon you!”. The Dwarves taught Khuzdul carefully to their children, as a learned language, not a cradle-tongue, and thus the language changed very little over the ages, unlike those of other races. The Dwarves also devised a secret language of gestures to communicate between themselves in silence, the iglishmêk.“
"The Dwarves used Angerthas, a runic writing system based on Cirth. There were different variations of Angerthas, which varied by each Dwarven clan; the Dwarves of Khazad-dum had their own variation and introduced a number of unsystematic changes in the system. The Dwarves of Erebor also used a further modification of the system, which was known as Angerthas Erebor. Some examples of Angerthas were seen in notable Dwarven texts, including the Book of Mazarbul, Thror’s Map, as well as other objects such as the Key to the hidden door, the key which was given to Thorin Oakenshield.”
“Dwarves were taught special skills by the Vala Aulë and spent most of their time crafting, smithing and mining in their massive underground cities. The Dwarves were some of the greatest miners ever to exist in Middle-earth. The Dwarves dug immense halls under mountains where they built their cities. Dwarven miners dug for precious minerals such as gold, iron, copper, and silver from all over mountains in Middle-earth, though the Dwarves considered coal mining degrading. In ancient times, the Dwarves found Mithril in the mines of Khazad-dûm. While mining in Erebor beneath the Lonely Mountains, they discovered the Arkenstone at the Heart of the Mountain."
"They were also capable masons and smiths - Dwarven smithing skills were said to be rivaled only by those of the Elves, and their masonry creations were bested by none. The skill of the Dwarves was unmatched; they crafted objects of great beauty out of diamond, emerald, ruby and sapphire. Everything Dwarven was beautifully crafted and intricate. They crafted many famed weapons, armors, and items of art and beauty, among them Narsil, the sword of Elendil, the Dragon-helm of Dor-lómin and the necklace Nauglamír."
"Dwarven armies were vast and powerful, and possessed vast legions of soldiers, cavalry and siege weapons, and their soldiers were equipped with powerful weapons, armors and tools for battle. Many different weapons were utilized by their soldiers, such as swords, axes, throwing axes, throwing knives, and warhammers."
"They had a knack for starting a fire almost anywhere out of almost anything. Although they knew how, Dwarves did not farm or herd often, as they preferred to spend their time underground mining and crafting. They rather traded crafted items with men and elves in exchange for food.”
“A descendant of nobility and a Dwarf Lord in his own right, Balin is one of the oldest members of The Company of Dwarves. Wise and gentle by nature, he has been forced to live a life fraught with war and the ongoing struggle for survival. Related to Thorin Oakenshield, Balin is one of his closest, most trusted advisers – but deep in his heart, this wisest and most loyal of Dwarves harbors troubling doubts about the wisdom of the Quest for the Lonely Mountain.”
