Days of Thunder

The Days of Thunder was an ancient period of Toril's history. This was the time of the fabled creator races, or Iqua-Tel'Quessir in the elven tongue, and many other races still hid in caves.

History
The Days of Thunder began when the majority of the glaciers left by the cooling of Abeir-Toril's ocean during the Shadow Epoch finally revealed a supercontinent that would eventually be called Merrouroboros. Life bloomed on this landmass in the form of the creator races and the ancient ape-like ancestors of humans.

Empires of the sarrukh, a sauroid creator race, arose around. The first was the realm of Okoth, which came to dominate much of the land that would be Faerûn over the next century.

Around, the sarrukh empire of Mhairshaulk was founded on the Chultan Peninsula.

Around, the sarrukh empire of Isstosseffifil was founded in the lands that would become Anauroch.

Around, Okoth fell after a century of civil unrest that caused many sarrukh to travel into the planes.

Around, the sarrukh founded the Ba'etith.

Around, the sarrukh empire of Mhairshaulk began its decline. The nation became the preserve of the yuan-ti. Meanwhile, the Batrachi Empires rose to prominence. The batrachi were an amphibioid creator race.

Around, the batrachi civilization reached its zenith under the guidance of Zhoukoudien. His reign ended when he was killed by the titan Omo in battle.

 * The changing of the stars: Batrachi released the Primordials from their prisons to turn the tide on their war against the titans. As the gods mobilized to stop their ancient foes, the primordial Asgoroth was determined to destroy the world if she could not control it. She threw an ice moon to the planet, creating the Sea of Fallen Stars. This event spurred Ao to separate Abeir-Toril into two different planets: Abeir and Toril.


 * The Tearfall: A rain of meteors fell to Faerûn, and the first dragons appeared shortly thereafter. Some scholars interpret the ancient texts as suggesting the meteors precipitated a dramatic climatic change, sparking the rapid evolution of proto-dragons into the various dragon species. Others claim the meteors were in fact falling dragon eggs, from which the varied races of dragonkind were born into this world.
 * Fall of the Batrachi Empires, as they were unable to survive the cataclysmic climatic changes brought by the Tearfall.
 * Rise of the Aearee Empires. The aearee (avian creator race) were the creators of the aarakocra, kenku and other birdlike humanoids.


 * c.
 * Lammasu Massacre: One thousand members of the Aearee-Krocaa empire were killed by a much smaller force of lammasu.
 * Experiments with domesticated landwyrms produce the first winged wyrms, which the aearee name wyverns. Thanks to its new wyvern armies, the Aearee-Krocaa empire greatly expanded their holdings in short time.


 * c.
 * The Wasting Plague: In a conflict between the gnolls of Urgnarash and the rookery of Kookrui-Shara, shamans of Yeenoghu summoned marrashi to blight aearee crops and spread a wasting plague among the avians. Decimated, many Aearee-Quor turned to the demon lord Pazrael for salvation.
