The illustration below would only happen in a world where the guilty are punished, the noble are victorious, and people can live happily ever. In other words, not in Westeros. Spoilers ahead.
Artist TheRealMcGee made this alternate ending for Tyrion's trial by combat, in which Oberyn Martell doesn't die beside the Mountain, but instead enjoys a victory kiss with his beloved Ellaria Sand. Presumably after this, Tywin accepted Tyrion with open arms, Jaime regrew his hand, and all the White Walkers mysteriously vanished from the world. Sigh.
TheRealMcGee also sells posters at Society6.
