The Protectorate Grand Alliance
While the Grand Alliance system was originally designed as an escalation and response to the impending unification of the Queendom of Arnast under Atue Runtoyek in 903QE, one such alliance stand apart from the others. The Protectorate Grand Alliance, called just The Protectorate by anyone that values efficiency, stands unified against a threat they'd argue is greater than the Dying Queen of war and death.
When the Age of Six came crashing down in 2419QE, it was said to be felt in every corner and crag of Enos. The event, known as the Hollowing of Draxus, left a twenty-mile deep crater in the earth, and tore Atue Omelolth's city of Xia from reality. Parts of it now hang suspended above the bruised ground in the The Queen's Crater, tended to by the shadows left from the impact of the explosion. Countless planar rifts were torn open, filling the forsaken pit with innumerable foul creatures that are only further warped and fractured by the ambient energies of the area. Those foolhardy adventurers that return from the crater often return with strange artifice that works on long-lost scientific principles, but have souls as hollowed as the crater itself.
Within three years of this event, The Protectorate was founded. What was once a continent teeming with countries that fought fiercely with one another in competition to always have the upper hand changed almost overnight to a unified front that could stop the spread of corruption from the crater. The dragonborn Atue's death left a psychic scar on the people she left behind, but took nearly half the population with her within the decade that followed, as to many, the Dying Queen of life and dragons was the one thing holding them supernaturally fast to this world.
