Fanlin'Deskor

Fanlin'Deskor (Amber Skies over Wondrous Rock in the draenei tongue) is the name given to a world by Velen, who witnessed its fall in a vision. The world's real name is unknown, as the Burning Legion invaded it and left nothing behind.

Geography
Fanlin'Deskor had four moons, an amber atmosphere, and rock formations made from the blue-tinted ground twisting in a thousand different ways. It was inhabited by various creatures. In the wake of the Burning Legion's invasion, the sky was so clouded with ash the moons could no longer be seen, and the rock formations had been blasted to dust. Nothing living remained.

Trivia

 * Just like Archimonde did in Dalaran, an eredar knelt in the dust and drew symbols of dread power with his finger, then the unleashed energies ripped the world's surface apart.
