The destruction of Valyria left a power vacuum in Essos. What followed the Doom of Valyria was struggle that lasted a century. In Tyrosh, Lys and Qohor, it is said that dragonlords were spared, but they did not long outlive the Doom. Some other dragonlords - those who had not been in Valyria when the Doom occurred - survived as well. House Targaryen had relocated to Dragonstone, the westernmost outpost of Valyria located in the narrow sea, twelve years before with their dragons, thereby ensuring their survival. The destruction of Valyria strongly reduced the number of dragonlords left in the known world. It is said that the fire and smoke was so hot that even dragons were consumed. Within mere hours, Valyria was gone and the Freehold was destroyed. In 102 BC the Valyrian Freehold collapsed when the Valyrian peninsula was destroyed in the Doom. The power of Valyria eventually encompassed the western half of Essos, ranging from the narrow sea to Slaver's Bay. The Valyrian Freehold defeated the Old Empire of Ghis and took control of the Slaver Cities, forced the Rhoynar into exile, and founded eight of the nine Free Cities- Braavos, the ninth and youngest of the Free Cities, was founded by escaped slaves from Valyria.
