Wisdom Hallyne begins by telling his audience that dragons were the key to the conquest of the Seven Kingdoms, but adds that to rule them, House Targaryen required a "less temperamental tool". When King Maegor Targaryen saw the work of the Alchemists' Guild, he blessed them with his patronage. Hallyne claims that at the time, alchemists commonly transmuted metals and performed other wonders, but the King was most interested in their mastery of "the Substance", which outsiders to the order dub "wildfire". To Hallyne, this is a slight misnomer caused by the popular belief that the Substance is uncontrollable: water doesn't extinguish it and steel can't repel it.
The order alone knows the secrets of the Substance. In bare stone cells beneath the Guildhall of the Alchemists, acolytes prepare the Substance with "utmost care and ancient magic". Apprentices then transport jars containing it to secure storage. The Substance's purity is then overseen by Wisdoms, such as Hallyne, who are adept in the alchemical mysteries. Hallyne claims that should an acolyte prove unworthy and let the Substance ignite, ceilings are "spelled" to collapse and fill the room with sand, for, once lit, the fire will only be extinguished by smothering or starvation.
For many years, the Guild faithfully served House Targaryen until they were overshadowed by the "envious" Order of Maesters, who dismissed all knowledge except their own, and by charlatans who hawked green paint, and worse, in their name. After the death of the unfortunate Prince Aerion Targaryen, who drunkenly boasted a draft of wildfire would transmute him into a dragon, the Guild lost its royal favor.
However, then came the "wise" King Aerys II Targaryen. Hallyne was only an acolyte when the King restored the Guild to its former glory, who, like his forefathers, appreciated the alchemists' secret arts, even naming Wisdom Rossart as Hand of the King. Together, the two punished Aerys' enemies "as befits a true Targaryen" - burning them alive. During the War of the Usurper, Hallyne heard rumors that King Aerys had commissioned the greatest Wisdoms to create a great weapon to employ against Robert Baratheon. Hallyne laments that the city may have fallen before it could be used. He also adds that many wisdoms disappeared during the sack of the city, victims to ignorance and envy, as ever.
Yet the order perseveres, like the Substance - which grows more potent with age -, and perfects its ancient arts in darkness, forgotten by the world. Hallyne boasts that they are masters of the fire, but live only to serve, and all they need is the right... "spark".
