Dragonstone is an island in Blackwater Bay in the crownlands. The island is located south of Crackclaw Point and Claw Isle, northeast of Driftmark, and north of the Gullet. It contains the castle of Dragonstone, the seat of House Baratheon of Dragonstone.
The castle of Dragonstone is a small fortress located on the face of the volcano. The nearby port contains inns, including a weathered little inn at the end of a stone pier. Farmers and fishermen live in villages below the Dragonmont.
Beneath Dragonmont are rich deposits of dragonglass. There is much obsidian seen in the old tunnels beneath the mountain, found in chunks and boulders. The greater part of it is black, but there is some green obsidian as well, some red, even purple.
Through the dalliances of many Targaryen lords and princes over the years, many of the smallfolk of the island are descendants of that dynasty, and are known as dragonseeds. Stannis Baratheon, Lord of Dragonstone, has outlawed prostitution on the island.
The isle of Dragonstone was settled two centuries before the Doom by Valyrians who defeated local lords of the narrow sea. They used magic to shape the castle of Dragonstone. When the maiden Daenys Targaryen had visions of the Doom, her father Aenar relocated his family, their five dragons, and all their wealth from the Valyrian peninsula to Dragonstone.
House Targaryen became powerful by controlling the Gullet and growing dragons in Dragonstone's hatcheries; the dragons Vhagar and Meraxes were born on their island, for instance. Although the Targaryens were sovereign, their island "kingdom" was not considered one of the Seven Kingdoms of Westeros.
Aegon the Conqueror, Lord of Dragonstone, invaded mainland Westeros and conquered six of the Seven Kingdoms with dragons in Aegon's Conquest. Quenton Qoherys, master-at-arms of Dragonstone, became Lord of Harrenhal after the burning of Black Harren. After their deaths, the bodies of Aegon and his successor, Aenys I Targaryen, were burned on Dragonstone in traditional Valyrian manner.
Dance of the Dragons
During the Dance of the Dragons, the island served as the early seat of power for Queen Rhaenyra Targaryen and her black council. She seized the Iron Throne after the fall of King's Landing. Lord Larys Strong smuggled King Aegon II Targaryen from the capital, however, and hid Aegon at a remote fishing village on Dragonstone, correctly believing that the queen would not think to look for her rival on her own island. Aegon's dragon, Sunfyre, eventually found its way to its dragonrider as well. With the assistance of Ser Alfred Broome and smallfolk, Aegon was able to take control the island and its castle. Rhaenyra returned to her island after the Storming of the Dragonpit. Unaware of the fall of Dragonstone, however, she was captured by Aegon's supporters and then fed to Sunfyre. The golden dragon eventually died there of its own wounds.
War of the Usurper
During the War of the Usurper, Prince Rhaegar Targaryen was killed by Robert Baratheon, Lord of Storm's End, in the Battle of the Trident. In response, King Aerys II Targaryen sent Queen Rhaella Targaryen with his new heir, Prince Viserys Targaryen, from King's Landing to Dragonstone. Nine months later, while a fierce storm destroyed the Targaryen fleet at Dragonstone, Rhaella died giving birth to Daenerys Targaryen.
Robert I, the new king after Aerys's death during the Sack of King's Landing, ordered his younger brother, Stannis Baratheon, to construct a new fleet and conquer Dragonstone from the remaining Targaryen loyalists. Ser Willem Darry fled with Viserys and Daenerys for the safety of the Braavosian coast before Stannis's ships arrived. Stannis commanded the successful assault on Dragonstone. Robert then granted the island and its castle to Stannis.

A Clash of Kings
During the War of the Five Kings, the poor lands of Dragonstone give King Stannis few supporters for his claim to the Iron Throne. For the past half-year no craft that has come within sight of Dragonstone has been allowed to leave again. The island's docks are full of ships for Stannis's royal fleet.
A Storm of Swords
Dragonstone's harbor and the dockside streets are largely empty since so many ships were destroyed in the Battle of the Blackwater. Disappointed in Stannis's defeat and considering Melisandre to be a sorceress, many smallfolk return to worshipping the Seven instead of the Lord of Light.
Once at the Wall Stannis sends word to Ser Rolland Storm to begin mining obsidian on the island. Stannis fears he will not hold his seat much longer but hopes that the Lord of Light shall grant them enough "frozen fire" to arm themselves against the Others before Dragonstone falls.
A Feast for Crows
With Stannis gone, only a few fishing ships remain to defend Dragonstone. The Redwyne fleet transports two thousand Lannister soldiers from King's Landing across Blackwater Bay, and Lord Paxter Redwyne encamps beneath the castle's walls.
Ser Loras Tyrell, realizing that the Redwyne ships are needed elsewhere after the taking of the Shields by the ironborn, volunteers to take command of the siege of Dragonstone, as he feels that Paxter's strategy of starving the castle will take too long. Lord Aurane Waters, the small council's master of ships, later reports to Queen Regent Cersei Lannister that Loras succeeding in taking Dragonstone, but was heavily wounded in doing so and there was high loss of life. Lord Hallyne asks permission from Cersei to allow the Alchemists' Guild access to any dragon eggs found on the island.
A Dance with Dragons
The Freehold's grasp had reached as far as Dragonstone, but never to the mainland of Westeros itself. Odd, that. Dragonstone is no more than a rock. The wealth was farther west, but they had dragons. Surely they knew that it was there.—thoughts of Tyrion Lannister
