Wildfire
A volatile green flame born from alchemy, capable of leveling stone and ending wars instantly.
Wildfire is a legendary alchemical substance known throughout Westeros for its devastating power in warfare. Resembling thick, glowing green liquid when dormant, it ignites into an intense flame that burns hotter than ordinary fire and resists extinguishment. Historically developed by the Maesters of Old Valyria, this volatile weapon became a closely guarded secret of the Crown, stored deep within vaults beneath the Red Keep in King's Landing to ensure the safety—or destruction—of the realm during times of crisis like the Dance of the Dragons.

Lore & Background
The origins of wildfire trace back to the ancient magic and science of Valyria before its fall. When the Targaryens rose to power in Westeros, they brought this knowledge with them, entrusting it to the Alchemists' Guild within the capital. These guild members perfected the formula, creating a substance that could be stored safely in glass jars until deployed against enemies. It became a symbol of the Crown's ultimate leverage, hidden from common knights and lords alike. During the Dance of the Dragons, the existence of these caches became a point of strategic tension between the factions. The substance emits no smoke when dormant but releases a pungent odor reminiscent of sulfur and rotting eggs upon ignition. Its green light is often described as unnatural, casting eerie shadows on stone walls. Because water only fuels its rage rather than quenching it, traditional firefighting methods are useless against a wildfire breach, making containment nearly impossible once spilled.
In Their Own Story
The damp air of the vaults beneath the Red Keep tasted of sulfur and old dust. A single lantern swung gently as the alchemist checked the seals on the glass jars lining the shelves. Their contents glowed with a sickly emerald pulse, humming with potential energy that made his skin prickle. He knew what lay above these stones—the throne room, the small council chambers, the lives of kings and queens. If the lock ever turned from the wrong side, this green fire would not just burn; it would erase history itself.
Reader's Guide
Wildfire functions as a high-yield incendiary weapon designed primarily for siegecraft and large-scale destruction within medieval warfare contexts. It is typically stored in thick glass vessels that can be shattered upon impact or launched via heavy catapults to rain fire upon enemy fortifications. Once ignited, the substance burns with an intense green flame that reaches temperatures far exceeding normal wood fires, melting stone and steel alike. The most critical property of wildfire is its unique reaction to water; attempting to douse it with liquid only causes the explosion to expand violently rather than quenching the heat. This makes it exceptionally dangerous for both attacker and defender if containment fails during transport or storage. Only specialized alchemists trained by the Guild are permitted to handle, transport, or neutralize the substance safely without risking catastrophic loss of life. In the political landscape of Westeros, control over wildfire stockpiles is a matter of supreme state security. The Crown maintains strict oversight through the Alchemists' Guild in King's Landing, ensuring that only loyal agents can access the vaults beneath the Red Keep. While powerful, its use requires careful planning to avoid destroying one's own position alongside the enemy target, making it a weapon of last resort for any ruler seeking total victory.
