The Infinity shards were believed to be splintered fragments of the Continuum Crystal, an immensely powerful conduit for interplanar rift energy within the distant continent of Tolria. Each shard possessed varying powers and affected their user differently, however, with the great power of the shards comes corrupting influence which seeps into the soul of those who attempt to use their power for their own ends. The shards were initially discovered by The Sunsations as they were being utilized by the Primarchs of the Sun as a source of their divine power.
