Location from A Song of Ice and Fire by George R.R. Martin
A volcanic island fortress off the coast of Westeros, shaped by Valyrian dragonlords into a castle of carved stone dragons — ancestral seat of House Targaryen before the Conquest.
Dragonstone is beautiful in the way a drawn blade is beautiful — there's menace in every line. The Valyrian architecture unsettles visitors from mainland Westeros; the stone seems almost alive, and on stormy nights the wind through the dragon carvings produces sounds that the garrison swears are roars. The island sits on massive deposits of dragonglass, a fact that seemed merely curious until the return of the White Walkers made it the most strategically valuable substance in the world. Stannis Baratheon held it and resented its bleakness. Daenerys landed here and wept. The castle remembers every Targaryen who sheltered within its walls, and the Painted Table — a carved map of Westeros that Aegon planned his conquest upon — still dominates the war room.
Black stone towers twist upward from the volcanic rock, every wall and arch carved into the shapes of dragons, gargoyles, and wyrms. The castle seems to have been grown rather than built, its Valyrian stonework fused by dragonfire into shapes no mason's chisel could achieve. Smoke sometimes drifts from the Dragonmont volcano behind it.
