Ballista Driver

Ballista Driver is arguably the most powerful being in existence, the only entity coming close to his level of power being Heron. A battle between Heron and Ballista Driver would be the equivalent of an unstoppable force meeting an immoveable object. Other than this, Ballista Driver is all there is, and all there ever will be. They say the extreme energy released when Ballista Driver died led to the creation of the Tsera Rune.
