Assassin's Fate ending. (Spoilers all rote books)

[Birwey]

So after finishing assassin's fate I went back and started rereading the series and I came across this prophecy"comes the catalyst,to make stone of flesh and flesh of stone at his touch shall be wakened the dragons of earth. the sleeping city shall tremble and waken to him. Comes the catalyst." So I kinda have a theory that fizts may come back. And I do admit I could just be that awakened stone is flesh like. So Thoughts?
Prophecy is from assassin's quest chapter 28 or about 69% of kindle.
