The trow were an ancient race once blessed by the goddess Nyx with the knowledge of iron, which they used over the years to wage a cruel campaign of conquest and enslavement. Strong, proud-willed and immortal, the trow are usually a force of destruction on the battlefield, though on rare occasions when they are close to death they will usually begin to petrify to avoid further damage. They were eventually shamed at the genocide they conducted against a revolting slave race into renouncing the use of iron, and were eventually buried beneath the surface for centuries awaiting release.
