Khaz Algar (Sector AR-938) is the other side of the world, exactly opposite to the Maelstrom. When the Maelstrom formed, as Aman'Thul ripped Y'shaarj from Azeroth's mantle, it caused a surge of Spirit to leak out over the content now known as Avaloren, from inside of Azeroth. This calmed the elements on that side of the world, allowing them to evolve and become the bedrock for a functioning society and blossoming civilization. They could co-exist with each other and mortals.
The titan-forged who went there became impacted by this, and have become one with the elements, infused by Spirit. They are able to master the storm because of it.
This "alternate" version of "order" is what infuriated Odyn. Because it both (in his eyes) corrupted his kin, but it also made a mockery of his world-view. Only Order, only the Titans, only he could bring about Order. Like his creator Aman'Thul, he probably bellowed "This is not Order!" at the sight of it all.
Much later, Erinithria arrived and started a brood of green dragons, which themselves would also become affected by the five elements.
Now, there is symbolism in all things. So just as the 5th element re-emerges on Azeroth so does the 5th Old God, which has become heavily tied to Spirit as well.
Spirit's opposite is Decay. The 5th Old God, as depicted in Chronicles III, is the Old God of Spirit and Decay.
