The Spring of Many Legacies

After the climactic battle between the Primordial forces of the Titans & the Divines, Elemental Lords & Dragons - the Divines cater this central portion of creation and agree to allow the Primordials to reign within the other half of the universe & retain their seats of power within the Elemental Chaos.
The Elemental Lords which aided the Divines against the Primordials were allowed to take their seats within their Elemental Planes and were so charged with the supervision of the banished Linnorm Wyrms. Though they each contested their planar regions with the arrival of the errant and superb powers of the Genies, spirits imbued with the essence of the elements that manifested in god-like form.
The Divine Gods that did not aid in the war were left to wander the Astral Sea.
The Primordial Green, Wisps & Loa were able to reinvigorate and rejuvenate the broken battleground of the world they called their home, striking an accord with the Divines to preserve the balance of the Spirit of Life, guarding the Dream and tasked with protecting the World Soul of Aetheus. They reached an accord through the intervention of a burgeoning keeper of the World Soul, Melora the Wildmother, a divine being born during the primeval ages. Though the Primordial Green keeps a close eye upon the remnants of the Evergrowth & the giant-kin children of Morgoron.
The Divines begin to shape the world of Aetheus according to their own will and accord. Here the world over the next few thousand years comes to take the forms of which we recognise in modern times, though slightly different. Melora the Wildmother helps form the bones and skeleton of the overworld from the defeated and felled Titans with the aid of Ergo the Soul Shaper, shaping the high mountains, planting the great forests and jungles, ebbing and flowing the rivers and streams, sealing the cold upon the edges of the world in the north and south. From these new lands, the Gods parcel these lands for the first of the founding races, and those that have claimed their own lands such as in Vangolia through the Goron line under Lorkhan the Storm Lord. Here, the gods walk the earth amongst their children, leading them to prosperity and tranquillity.
The most powerful of the races came to be the true Giants, (those of whom were the children of the Titan Annam & Melora the Wildmother), the true Dragons (the western winged-dragons) and the rising & immortal Primal Elves.
The Divines begin to guide the other races across the world, growing and spreading across the lands in burgeoning civilisations - meanwhile, the Dragons and Giants are already the greatest powers capable of magic & runes.
The Greater Gods of the dwarves and elves, stoic Ergo the Soul Forger & the mysterious Arvanos the Arch-Heart in the meantime complete the grand re-ordering of the cosmos through the Planar Reformation. Setting the boundaries between the Prime Material Plane, the Feywild & Shadowfell, the Ethereal Plane & Fugue Plane, the Elemental Planes, the Elemental Chaos, the Astral Sea and lastly the Outer Planes. Shaping this centre of the universe as the seat of the Divines creation and great masterpiece.
