Dust & Rain

Fifteen years ago, a brilliant scientist built a barrier against the dangerous power that radiates from the City of Glass in the southern land, allowing the citizens of Chevakia to live without fear of their lives. Since then, the democracy of Chevakia has prospered, with free-thinking scientists developing steam power and the beginnings of electricity.
But the power, which they call sonorics, controls the weather in Chevakia.
Senator Sadorius han Chevonian is the country's chief meteorologist. While taking measurements for his job, he is the first to notice a rapid rise of sonorics levels out-of-season. The senate is locked in trivial debate, and to make them listen, he has to take a step he never thought to make.
After the huge explosion of the machine they call the Heart of the City, Loriane has fled the southern land with the sorcerer Tandor, who hovers in and out of consciousness. But while Tandor isn't speaking, she cannot confirm her fears that he caused the explosion, and that the child she carries has something to do with his twisted plans to seize power from the Eagle Knights who rule the City of Glass.
Just before the explosion, southern queen Jevaithi fled into Chevakia with her young lover Isandor. While they think they're free of the tyranny of the Eagle Knights, it soon becomes clear something very bad has happened in the City of Glass soon after their escape. Something so bad that it sends waves of sonorics into Chevakia, causing even the Chevakians to flee.
Several streams of refugees are heading for the Chevakian capital. Southerners by train, Chevakians by road, into a city that is tragically unprepared, a country in turmoil with a leader whose support hangs by the merest thread.
