The Fall of the Dhakaani Empire

"The effects and costs of the Dealkyr War on the Dhakaani cannot be understated. What had once been a machine, every part of it working toward a shared goal. The corruption that the Dealkyr sowed in their society destroyed the underlying assumption of that machinery, and it simply couldn't work anymore. The empire limped on, but hounded by corruption, rebellion, and internal strife, until it finally broke down."
