The Thunder Lords
The Thunder Lords are a group of storm titans that inhabit the titanic maelstrom known as the Eye of Io. These tempestuous giants have the power to unleash the Eye of Io upon the world, and so the Sea Kings pay them tribute to keep the great storm “trapped” above the southern pole.
It is rumored that the Thunder Lords serve a powerful being or force of nature called the Harridan. Whether they serve the Harridan out of fear or respect is unknown. Scholars speculate that the Harridan might be an exarch of the goddess Melora, a monstrous kraken or leviathan that stirs the sea beneath the storm, or a forsaken sibling of Bahamut and Tiamat.
