Storia di Westeros 3. Gli Estranei attaccano i Primi Uomini, ma sono sconfitti.

A Mapped History of A Song of Ice and Fire. Part III
(by HotbrownDoubleDouble)

ca. 8, 000 years before Aegon’s Conquest
In this time, night seems to last for a generation, and the longest, coldest and darkest winter descends on Westeros. The ice spreads down from the north, and under the cover of darkness, the Others invade Westeros from the uttermost north, marching, killing and raising up the dead to be their servants in unlife and nearly destroying all men in Westeros. The Long Night comes to an end with the Battle for the Dawn. The children and the First Men unite to defeat the Others with dragonglass weapons, with the Night's Watch pushing them back into the frozen reaches of the Far North. Legendary figures from this time include the last hero and Azor Ahai, who wields a great sword of fire, Lightbringer.
With the Others defeated, Bran the Builder, with the aid of giants, the First Men, and perhaps the children of the forest, raises the Wall: a monumental fortification of ice and ancient magic, to shelter the realms of men from the menaces of the north. The Sworn Brotherhood of the Night's Watch guards the Wall.
