The Doom of Valyria, often referred to as the Doom, was a cataclysm which caused the collapse of the Valyrian Freehold. The Valyrian Freehold had expanded their power wealth for five thousand years, until one fateful day in 114 BC when every hill for five hundred miles exploded, filling the air with ash, smoke and fire, so hot that even the dragons did not survive. Buildings and entire towns were destroyed by earthquakes, while lakes began to boil. The Fourteen Flames erupted, sending molten rock into the air, and red clouds rained down dragonglass. The Valyrian peninsula broke into several smaller islands, and the Smoking Sea formed between them. A tsunami resulting from the disaster destroyed Velos and Ghozai, located on the nearby Isle of Cedars.
