Age of Flies (Shard Ne'Vaal Supplement)
From D&D Wiki
Following the failure to come together in the previous age, the gods had begun to tire of the bloodshed and thus sought to resolve the issue by diving into the fray themselves. The results were calamitous as they struck upon the pangaea and destroyed it, scattering the lands into the more recent Old World. As the continents drifted apart, the wounds left in populations bled and many died in the disastrous transition. It is said some cities were covered in flies as a result of all the dead.
