Asura, the little goblin-y, flappy-eared tinkerer creatures… They make magic machines, right? They’re tinkerers, yes, but also intuitively powerful masters of the elemental energies surrounding them in the caverns of their native sub-Tyrian world.
The talents of the asura carried their civilization through ages of harmonious existence beneath the lands of Tyria. When the destroyers forced them to the surface, their truly exotic technology and traditions flooded out and changed the world.
