Once Upon A Time:
GDW Game Designers' Workshop started publication of a trilogy set in The New Era: three Traveller novels by Paul Brunette chronicling a ship and its crew in the chaos after the rebellion. It started with The Death of Wisdom, and continued with To Dream of Chaos, but GDW (like the Third Imperium) was embroiled in chaos, and closed it doors in 1996, without releasing the third novel.
Ten years later, Marc Miller wanted to know how it ended. The manuscript for the original third novel was lost, so Marc teamed up with writer Matthew Carson to puzzle out the truth.
They read and outlined the first two novels, and from that developed their own ideas of the story arc. Then they compared notes and outlined the third novel... a suitable ending to the stories that went before.
Matthew then commenced writing, and over the course of two years produced a 300,000 word manuscript that tied up the loose ends and resolved the story line.
Who Would Have Imagined?
That at that point, the original manuscript emerged from the secret archives of GDW! Now there were TWO manuscripts... the TNE trilogy had TWO endings: the original and the alternate. The work by Miller and Carson make the alternate ending the preferred climax to the series, but there is still the original manuscript to consider. Which one is better? Which one more faithfully carries the story line forward?
Both are now available at DriveThruRPG.
