The Great Long Dark

From the introduction: Thirty years ago your parents fled from the Tyrant’s Kingdom. They packed their things in secret, and prepared to make the long hard journey through the underground, to freedom. As they went they made a promise to the suffering many they left behind. To the brothers, sisters, uncles, and friends, who lived under the Tyrant’s yoke in daily fear. Your parents promised to return, as soon as they could. To return with steel, and iron, and vengeance. To return and rescue those who remained.
