ASOIAF:Möngke Khal
12,000 years ago, the First Men came from the Eastern continent to Westeros, and their beliefs sparked a war with the native Children of the Forest. An oath was made between the two sides: the forests would remain the possession of the Children of the Forest, and the rest of Westeros would belong to the ancestors.
6,000 years ago, the Andals invaded Westeros from the Eastern continent, conquering the southern lands.
300 years ago, the Valyrians, led by the conqueror Aegon Targaryen from the Eastern continent, began the conquest of Westeros.
Now, the Supreme Khal, Conqueror of the Eastern Continent –:Möngke, leads the Dothraki across the Narrow Sea, seeking permission to declare himself King of the Andals, the Rhoynar, and the First Men, ruler of the Seven Kingdoms and protector of all the lands.
