No. That outcome was explicitly ruled out by the Prediction. All speaking units would be croaked, and that obviously includes Digdoug. "All speaking units" must be a common phrase in Erf, usually implying that everything will be croaked. Otherwise its specificity should seem odd.Omnimancer wrote:The prediction may have saved Digdoug's life, but it also seems quite possible that if he had stayed the city would have been strong enough to repel an invasion without serious casualties.
Anyway, one could legitimately ask if there would have been a different outcome had there been no Prediction, but we do not know the answer to that. We only know that once a Prediction is cast then one of a certain set of outcomes must then occur, and others are rendered impossible.
If one does ask if the city might have been more successful had there been no Prediction and had Digdoug remained, but I think the answer is no. I am going to assume that Predictions are by default not self-fulfilling. In other words, the predictomancer looked into the misty future and saw the default condition that would have occurred had no Prediction been made: Digdoug stayed in the city of Weatherbug and helped fight off the attack. The predictomancer saw that leading to great loss of life and reported it as such (all speaking units.. croaked). Otherwise, if we allow that predictomancers try to make you fulfill the Prediction--in this case by removing Digdoug from the city when otherwise his remaining there would have been excellent--then we have to say that no one would ever hire a predictomancer under any circumstances because the results are at best useless and perhaps detrimental, in this case causing the loss of Lady Chains and her forces when they might otherwise have survived.
We must assume that a Prediction is what would have happened had there been no Prediction. What makes them strange and extremely powerful is that they will continue to happen even if you try to circumvent them, which is probably why you can often find odd loopholes in their phrasing. I like to imagine that the Titans exist outside of time in Erf and sit around a table playing a game, crafting Predictions in such a way that they always come true, and maybe losing points for actively interfering with numbers in order to make it work.
