Having experienced the important moments of the unnamed mage's life, Reve was privy to certain things....and one of them was the hidden details of the shards of Sheol!
So, what were these shards?
The shards represented the greatest sin of Arcadians. It was living proof of the sordid sacrifice the people of Arcadia paid to relieve themselves of the Annihilation Wars.
The series of wars caused by the titans were never-ending. This was due to the innate stubbornness of a titan. They had the ability to propagate and build up a colony fast. They could quickly recover from a previous war and spend the next five hundred years hiding and accumulating forces.
Going with this flow, it was easily understood that there would be no end to the wars if nothing new was brought to the table.
