The Great Thaw was the name for the spring immediately following the devastating cold of the Great Winter Frost.
Summary[]
The spring from 406 to 411 AC was most notable for the Tourney of King's Landing (406AC), a six week long affair celebrating the end of the Great Winter Frost. The prize for the winners of the three jousts were positions amongst King Trystane Baratheon's Kingsguard, and the three winners, Ser Gerris Dayne, Ser Henly Merryweather, and Ser Gallard Templeton, were named the Knights of Spring.
