There is one obvious exception to this, and that is the war between the Eladrin of Sul’erais and the Confederacy of Goblin States. The war lasted over a hundred years, the two states warring over the land at the mouth of the Kul’Seris River. Eventually conventional warfare slowed, and sorcery took over. The Eladrin would create a ritual to devastate the goblin’s homeland, and the goblins would fire back by cursing the Eladrin’s water supply. This magical war escalated, with the final straw for the Eladrin being when the Hobgoblins sealed off their access to the Feywild, where most of the race’s leadership lived. It was not the goblins though, that were responsible for the world’s devastation, but a charismatic Eladrin sorcerer named Kulmair Devisheil. With most of the Eladrin leadership sealed into the feywild, Kulmair rose to power quickly, assuming leadership over the Eladrin. He slowly pulled the nation’s wizards away from working on a way to reopen their portals to the feywild, and instead focused on a new ritual. One that would bind to their will the mightiest being they could think of: The God Bahamut.
The ritual was cast with the intentions to bind one of the most powerful gods into service, but it did not work as intended. When Bahamut was brought to the mortal plane he refused to be a slave to mortals, and with no other option available, he sacrificed himself and caused what is now referred to largely as The Cataclysm.
