This formidable destruction weapon was incarnated from one of the "Dragon Bones of Destruction". These wedges were infused with the power of the Dragon Deity "Gyze", and absorbed the spirits from the surroundings to manifest their flesh forms. "Gyze" identified this being as "Drachma" while Messiah's forces referred to it as "Inferno", the latter being more frequently used in documents. The continent with the most abundant dragon veins---this wedge was driven into the land which would become Dragon Empire of modern days, and was considered the most powerful among all Zeroth Dragons, at the cost of difficulty to control. As Gyze dominated all lands of Cray, Drachma had destroyed nearly half of the continent. Drachma was finally outmatched by a warrior, whose dual swords were referred to as "Swords of Apocalypse" and passed on to mighty generals of the later generations.
Note: The "Dragon Veins" is a Feng Shui concept of invisible lines of power beneath the land, akin to "ley lines".
