They Live

CS Lewis wrote somewhere (I think) that Christianity is the story that everyone would most like to be true. Surely not! However, on reflection, I think that he must have meant one aspect of Christianity, not the scourging and the impalement, just the discovery that a friend, who had been thought to be dead, is alive. 

Authors can write apparent deaths followed by unexpected returns in works of fiction. Another way to revive a character who has died is in a prequel. If we read Poul Anderson's History of Technic Civilization in its original order of book publication, then:

the Polesotechnic League fills the first four volumes;

the end of the fourth volume, Mirkheim, is written as an elaborate farewell to several continuing characters;

the fifth volume, The People Of The Wind, set centuries later, refers historically to League merchant David Falkayn as the Founder of the colony on Avalon;

the sixth volume, The Earth Book Of Stormgate, fictitiously published in the aftermath of the events of The People Of The Wind, opens with an Avalonian Ythrian introducing twelve stories that will illuminate the circumstances of the founding of Avalon;

eight of these twelve works are a second Polesotechnic League series featuring all of the characters whose stories had been brought to an end at the conclusion of Mirkheim!

They live again.
