Everyone agrees that Lucinda should have been born a witch, with her personality and obsession with the Fire Guild. Or was she born a witch? Unaware that she's putting herself on the frontline of the coming war with the neighboring Empire she petitions the Fire Warlock for assistance in finding a husband. Living in his fortress with access to his library and studying with the handsome flame mage Sven is a dream come true except Lucinda keeps having nightmares. The King is convinced that the Fire Warlock, Quicksilver, is a power hungry wizard holding back the nobility out of spite and Lucinda has learned that the situation is hopelessly complicated. The Office of the Western Gate, that grants the Fire Warlock the ability to draw on the power of the volcano Storm King, is a magical construct known as a Lock. The Fire Warlock is charged with protecting the border and if the Warlock fails to act the Lock will simply incinerate him and pass the mandate to his successor. Above all, the Lock will maintain the sovereignty of Frankland, even if the inability to surrender in a war means their utter destruction. If only there was another warlock with the gift to craft Locks who could fix things because the seers agree that Quicksilver won't be the Warlock much longer.
