Batrachi were an amphibious race that are counted as one of the Creator Races.
- -33500 (Dalesreckoning): The Batrachi found kingdoms of their own.
- -31000 (Dalesreckoning): The Batrachi unleash several once-imprisoned primordials against Annam, lord of giants and titans, and his colossal brood. The gods, furiously oppose the primordials which leads to catastrophic disaster across all of Toril, including a period of seven years of darkness and cold which the Batrachi call the Seven-Turn Winter. As the war rages on, many Batrachi escape to Limbo. Soon after, they found the Supreme Throne. In reaction to the destruction wrought by the war of god versus primordial and batrachi, Ao splits the world into two twin worlds, slightly out of phase with one another. One is called Abeir, and dominion over this twin of Toril is given to the primordials. Toril, the original world is placed under divine rule. 
The Batrachi EmpiresEditKolophoon, Boitumelo, Nadezhda, Zhoukoudien and Pourounkorokale were the Batrachi Empires.
Pourounkorokale was located underneath the Shining Sea. The tako ruled over tribes of kuo-toa, locathah, and other species of aquatic batrachi. Pourounkorokale fell after the fall of the other Batrachi empires due to dragon attacks and the betrayal by their sahuagin allies. Survivors fled through the Strait of Lopango into the Sea of Corynactis.
The abolethic Kolophoon Sovereignty ruled over the lands surrounding and beneath the modern day Wizards Reach and Alamber Sea. Kopru and froghemoth were their servitors. Presumably these batrachi opened the first gates to the Far Realm and unleashed the Abolethic Sovereignty upon Abeir-Toril.
