To accomplish this goal, the blade was infused with tremendous radiant magical power, as well as some space-time manipulation powers.
While the blade was not created to be an intelligent magical item, some of the groundwork for such a capacity was laid so that the blade could be given a series of commands that could be executed autonomously. It was this sort of arcane computer that gave rise to Iris Four.
By the time the party arrived, the blade was already a part of Iris Four. After her defeat, the blade was taken by the party for the Hexelemental Drive and a smaller crystal at the hilt of the weapon was taken by Raziela the Shroud.
