You know how i operate, that I do not spoil anything in regard of my story, but I will tell you a few things vaguely :)
Daemion is around for Dance of Dragons, which the timing of Dance, for the sake of story, has also changed. But you can be sure that he will be an older man by then… and Dance? Let us say every single Targaryen will be beyond just impacted by it.
I will say this too: be open to anything that may come to pass for Daemion the Black Dragon’s bloodline… anything is possible.
I did cover a small thing in chapter 100 of dragon’s legacy, that Daemion will be Remembered, more than anything, his *Deeds*, rivers of blood. But no need to worry, because if the Burden of Legacy and the third instalment are received well, I will do a fourth instalment as the final instalment and a conclusion of to the entire saga of not just The Legacy Trilogy, but also for A song of ice and fire and the Great War against the Others.
