A sister city of old Valyria, lost in the same Doom that claimed Oros and a dozen others, TyriaÔÇÖs ruin sits silent through the Dance of the Dragons exactly as it sits silent through every other Westerosi war ÔÇö a monument to a catastrophe no dragon since has come close to matching.

No death the chronicle records has come to this ground ÔÇö or none the maesters have set down.
