Wanderlust: The Exodar
According to lore, the Draenei crashed their big, curvaceous ship smack into an island off the coast of Kalimdor. They converted the biggest chunk of that wreckage into their capital city, which shares the name of the ship: The Exodar.
Aside from a lack of right angles, the primary design element is the crystal. They come in many shapes and sizes, and each one glows with untapped energy.
The little carbuncles depicted here are striking and beautiful, a perfect first glimpse of the design as one walks the long, winding passage into the four primary chambers of the city. I picked this location also because it maintains the design conceit in the Draenei architecture; they crashed here, and the broken bits and chunks litter the landscape around Azuremyst Isle.
