Royal Zero (Familiar of Zero AU/SI)

The power of the void is a potent thing. The magic of the Founder Brimir, once thought lost to time. One shard for each of the four nations that were created after his passing. One that snaked its way through each nation's royal lineages, and their offshoots. But what would happen if the lineage of the Void ran true? What would happen if instead of a girl with pink hair who called forth a familiar, but rather one with purple?
