What did really happen in that fateful month of March? Where had Callum and Rayla gone? Why had the plague stopped so suddenly? What had happened to Tiadrin in the last fourteen years, and why, despite the researches, no one had ever been able to find her? Why did King Ezran forbid all citizens of Katolis to climb Mount Kalik?

Still, no historian has been able to give a satisfactory answer to these questions. And yet, the coincidence of the dates of Callum and Rayla's disappearance with that of the end of the plague, the inexplicable discovery of their daughter, and the mysterious silence of the sources over the whole matter has convinced more than one scholar that these events must somehow be connected.

I cannot give a definitive answer to the mystery, but in the many years I spent collecting the sources of the time I found some interesting clues that can at least give us some guidance. What I'm about to present is a personal theory of mine, and I am aware that many of the more traditionalist historians will turn their noses to it: Therefore, instead of setting out my hypothesis here, I will put it at the bottom of the book as an appendix. In this way, the reader will be free to decide whether to read it or not, and whether to believe it or not, without this affecting the rest of my work.

Personally, I am convinced that mine is the only theory capable of answering all the mysteries surrounding the end of the Green Plague. But in the end, the truth is known only by the gods.
