"The Legends of the Nameless World cycle" includes the stories of key characters of the "Dragon Heart" saga. "Ash" is the first of the prequels to the "Dragon Heart" series. It can be read as a stand-alone book.
Even before Myristal went out, before the battle of the Heavens and the Earth broke out, before the Black General was imprisoned on the Mountain of Skulls, a wizard had wandered the endless expanses of the Nameless World in search of his past and his future. This is the legend of Ash, the Master of a Thousand Words, the Bloody General. What’s true and what is fiction is up to you to decide. But this is how his story was told to young children, so that they wouldn’t be afraid and have nightmares, back when the legends of the old world were still remembered.
