story identification - Looking for a book about a slave that gathers friends and goes into a desert to find a dragon

I remember reading this book back in late 90's. It is about a slave that gathers some friends and goes into a desert to find/fight a dragon. There is also a revolt/uprising in the slaves' home town. I can't remember if this is a single book or a trilogy.

I think the rulers were called Sorcerer-lords or Sorcerer-Kings. And I remember one character was called Boris or Borys.

Answer

In the Dark Sun D&D setting, Borys is the name of the first Athasian dragon who was the Sorcerer-King of Ur-Draxa. There are about a dozen novels set on Athas; the entire world is a desert and slaves are a constant of the setting so it's difficult to narrow it down to one in particular, but it's almost certainly one of these.
