Wildfire is a flammable liquid which is created and controlled by the Alchemists’ Guild, an ancient society of learned men using arcane knowledge and is now based in the city of King’s Landing. Wildfire is a highly volatile material; when ignited, it can explode with tremendous force and the resulting fire burns so hot that water cannot extinguish it. Only by smothering the flames with large quantities of sand can they be put out.
