Year of the Nativity of Christ 1666. The king and parliament are fighting for power, using both troops and intrigues. At the courtyard of marvels deep below, in the bowels of London, there are also enough enemies. Old customs are bursting at the seams, and no one knows what will replace them. But the danger is coming even more terrible - the one that is capable of destroying everything. In the house of a sleeping baker, a spark flies out of the oven, and a fire ignites from that spark, which will burn London to the ground. While people struggle with flames devouring street after street, the brave go out to battle the enemy not so tangible - with the very spirit of the Great Fire, able to incinerate everything in its path. Mortals and marvels will have to forget about everything that separates them, and together, shoulder to shoulder, fight for the life of London itself...
