Dragonglass
The black stone that shatters ice giants and turns the tide of eternal winter.
Dragonglass, the volcanic glass known to geologists as obsidian, lies hidden within the jagged peaks of Dragonstone and in the frozen wastes beneath Castle Black. For millennia, the southern kingdoms dismissed it as nothing more than a curious black stone—fit only for child's play or crude tools. But when the Long Night returned and ice giants marched across the snow, this brittle material revealed its true purpose: it is one of the few substances in existence capable of shattering the White Walkers.

Lore & Background
Born where volcanic fire meets eternal frost, dragonglass forms a natural glass so sharp it can slice through flesh as easily as butter. Unlike Valyrian steel, which requires dragonfire and sorcery to forge an edge that lasts centuries, dragonglass is inherently fragile; a single heavy blow against stone can shatter the blade into dust. Yet, this fragility matters little when facing the dead. Its unique property of instantly disintegrating a White Walker on contact renders it more valuable than any king's ransom. In the modern era, Samwell Tarly's research identified vast deposits beneath Dragonstone and recognized its lethal potential against the army of the dead, marking the true turning point in the war.
In Their Own Story
The wind howled through the ruins of the Fist of the First Men, carrying a scent of ozone and rot. A White Walker emerged from the blizzard, eyes burning with cold blue fire, raising a sword of ice that seemed to suck the warmth from the very air. Before it stood a man armed not with steel, but with a jagged shard of black glass pulled hours prior from the frozen earth. As the Walker lunged, the man did not flinch. He thrust forward; where the black stone met the ice blade, there was no clang of metal, only a sharp crack like thunder. The Walker froze, its blue light flickering violently before it shattered into a million shards of frost, leaving nothing but silence in the snow.
Reader's Guide
In ancient times, the Children of the Forest and the First Men wielded dragonglass to hold back the Long Night. In the modern era, Samwell Tarly taught the Night's Watch and Jon Snow how to forge arrows, spearheads, and daggers from the stone. With major deposits located on Dragonstone and within the mountains beyond the Wall, it has become a critical strategic resource for any army preparing to face the threat of the dead.
Did You Know?
- Dragonglass was used by the Children of the Forest to create the first weapons against the Others thousands of years ago.
- Unlike Valyrian steel, which is forged with magic and dragonfire, dragonglass is a naturally occurring volcanic glass.
- The Night's Watch had access to vast caches of dragonglass beneath Castle Black but largely ignored them until the White Walkers returned.
- Dragonglass can be carved into intricate shapes for weapons like daggers and arrowheads, whereas weirwood faces are carved from the heart trees themselves.
Frequently Asked Questions
What exactly is Dragonglass?
It is a naturally occurring volcanic glass, scientifically known as obsidian, found primarily in Dragonstone and the Frostfangs. While often mistaken for a useless black stone by southern kingdoms, it holds significant magical properties against supernatural threats.
How does Dragonglass kill White Walkers?
Its most critical ability is the power to kill White Walkers instantly upon physical contact. Unlike steel or wood, this brittle material can shatter the ice giants that lead the Night King’s army.
Where are the major sources of Dragonglass located?
Major deposits are hidden beneath Eastwatch-by-the-Sea and within the jagged peaks of Dragonstone island. These locations were historically overlooked until the return of the Long Night made the resource vital for survival.
Why is Dragonglass essential during the Long Night?
It serves as a crucial weapon against the Army of the Dead when Valyrian steel becomes too scarce to equip all soldiers. Without it, humanity would likely have been extinguished during the Battle of Winterfell.
How did the First Men historically use Dragonglass?
The First Men originally fashioned it into crude tools and weapons long before dragons arrived in Westeros. Later generations rediscovered its lethal potential as a necessary alternative to forged steel for hunting ice demons.
