jan 1, 100 BC - Doom of Valyria 100 BC

Description:

The Doom of Valyria takes place. The nature of the Doom is unclear, save that heavy volcanic activity is involved. The Valyrian Peninsula is shattered and the city of Valyria is laid waste, although not completely destroyed. The dragons of Valyria are virtually wiped out. The Valyrian Freehold fractures apart. The western coastal cities become independent, naming themselves the Free Cities. Braavos reveals itself to the other cities, eventually becoming the most powerful of them through their vast fleet and economic power. The cities of Slaver's Bay become independent again, although Ghiscari power begins building again in the south. The warrior-nomads of the vast eastern plains become more emboldened by the fall of Valyria and their dominant tribe, the Dothraki, begins raiding the surrounding lands. The Targaryens remain safe on Dragonstone, the guardians of possibly the last three dragons in the western world. The Targaryens reject a request for aid from the rulers of Volantis is conquering the other Free Cities in the name of Valyria. The century following the Doom becomes known as the Bleeding Years.
