Tales of Vesperia

In the world of Terca Lumireis, cities are protected from monsters by ancient devices called blastia, powered by a mysterious energy known as aer. Yuri Lowell, a former Imperial Knight from the lower quarter of the capital Zaphias, becomes involved in a journey after pursuing a stolen blastia core. Along the way he meets Estellise, a noble young woman searching for Yuri's childhood friend Flynn. Their travels bring them into conflict with corrupt officials, guilds, monsters and the growing danger surrounding the world's dependence on blastia.
