According to legend, the Nullifers were a group of unimaginably evil beings that once ravaged the world. They were opposed by Lord Casterwill, the first Seeker, who summoned the Titans to Earth using the Amulet of Will to fight a war against this threat. After a 500-year conflict, Lord Casterwill was able to seal the Nullifiers in the Spiral Mark with a powerful spell. This spell could only be broken by the Willblade and the power of Void on the longest night of the year with the Red Comet approaching Earth.
