Blastia is a technology created by an ancient civilization called the Krityans on the planet of Terca Lumireis in Tales of Vesperia
. The technology has a wide range of uses such as powering ships, providing water or in extreme cases producing barriers that protect entire cities from the monsters that have overrun the planet.
Bodhi Blastia (body blastia) is also used by Imperial knights and Guild members to enhance their combat abilities. Blastia are powered by "aer", a substance that permeates the
entire universe and lends its power to the blastia. However aer can gather
around blastia and in high concentrations become fatal to humans
