A game about intrigue and adventures, about the deeds of single characters and the struggles of entire populations, about the fate of lonely heroes and the destinies of nations and tribes.
A Land of Ice and Blades was born to try to emulate epic grand stories (ASOIAF?) by using the engine of Apocalypse World (and its S&S/dark hacks such as Dark Age and Fallen Empires and A Storm Eternal).
It starts with some world-building done all together at the table, then the game runs with a set of "table moves" that dictate the times of scenes, episodes and seasons, and with a rotating Game Master.
