Welcome to Know Your Lore, where each week Alex Ziebart brings you a tasty little morsel of lore to wrap your mind around. Sweet, sweet lore. Mmmm.
In the spirit of the Midsummer Fire Festival, We're going to take a look at the Elemental Lords, one of which was the inspiration for this holiday. The Elemental Lords were originally agents of the Old Gods, and some of their most powerful ones at that. They were used to do little more than sew chaos in Azeroth and keep it in a constant state of disorder.
As we know, the Old Gods didn't hold up very well against the Titans and their champion, Sargeras. When the Old Gods were beaten, bloodied, and chained far beneath the earth, their Elemental Lieutenants received similar treatment. All four of them were banished from the plane of mortals, trapped within an Elemenal Plane, where they could cause as much trouble amongst themselves as they wanted without bothering Azeroth.
Of course, long after the Pantheon no longer had an active hand on Azeroth, the mortal races did catastrophically dumb things as they usually do and ruined it for everybody.
