Location from The Lord of the Rings by J.R.R. Tolkien
The Lonely Mountain — a Dwarf kingdom of unimaginable wealth carved into a solitary peak, reclaimed from the dragon Smaug and now the mightiest Dwarf-hold in Middle-earth.
Erebor hums. The mountain is alive with Dwarven industry — the ring of hammers on metal, the rush of bellows, the grinding of stone-cutting wheels reverberating through corridors that amplify and carry sound for miles. The air is warm from the forges, thick with the smell of hot metal and stone dust and lamp oil. The deeper you go, the warmer it gets, and the more the mountain feels like a living thing with the Dwarves as its blood. The wealth of Erebor is difficult to comprehend. Smaug slept on a bed of gold coins deep enough to drown in, and the Dwarves have been adding to the hoard since reclaiming their home. But the treasure carries a memory of dragon-sickness — the consuming greed that drove Thorin mad and nearly destroyed the alliance at the Battle of Five Armies. Dáin rules wisely, but the gold whispers. It always whispers.
A single massive mountain rising from the plains, visible for leagues in every direction. The Front Gate — an enormous archway carved into the mountain's southern face, flanked by stone Dwarf sentinels. Inside: vast halls with pillars carved from living rock, veins of gold and gems glittering in the walls, forges that light the deep places with a warm orange glow. The Great Hall of Thrór with its throne. Mine-shafts descending into darkness. The treasure hoard — mountains of gold, gems, and crafted objects filling chambers the size of cathedrals.
