I Have a Book of Predictions

This is a book about swords and sorcery. There are legendary stories about the predecessors who traveled through time; There was the Great Schism, the Crusades, the Pope and the Patriarch each excommunicating the other; There was a fierce collision between royal power and religious power, with the loser begging the other party for forgiveness with bare feet in the ice and snow; There are legends of dragon-slaying warriors from small mercenary groups, and there are also large mercenary groups with large numbers of people garrisoned in the city to assist in defense, fighting to the death and fighting to the last man; When aliens invaded, a lord with a prosperous city turned away, while a down-and-out donkey knight fought alone, staining the territory with blood; A pregnant girl runs away from home just to practice elopement; There are also heroic young people who support the crisis and turn the tide.
