Tens of thousands of years ago, the vast continent of Sarlona was the cradle of human civilization. Three thousand years ago, the first human colonists set forth from Sarlona, setting in motion the events that would shape modern-day Khorvaire. Over the past fifteen hundred years, Sarlona has become an insular land of mystery. This change is due to the influence of the Inspired, a powerful dynasty of psychic overlords who serve as vessels for quori from Dal Quor. The continent is devoid of either Eberron or Siberys dragonshards.
Once, Sarlona was home to over a dozen distinct kingdoms, but today only two established nations remain: the mighty empire of Riedra and the mountain sanctuary of Adar.
