The Jeweled Desert
Three strangers receive letters from a man calling himself the One-Eyed Khan, telling them to meet for a job in the expansive Jeweled Desert. He promises them gold and a way into the Ruby City, or Rubaya, as a reward.
The desert is a place of strange creatures, interesting people, and legendary places. You can die out in the dunes or in the alleyways of a town, or you can prosper. Either way, Sariel the bounty hunter, Ecstasy the ex-con, and Mira the alchemist have the weight of the most powerful person in the Empire, except perhaps the Emperor himself, behind them.
