Odds are we have to delay a turn regardless. Everyone will go BUT OMENS so they will be hypersensitive and overreact to any bad eventsIf the doom comet does come, then opening the mine will probably lead to "everyone 'knows' that the mine brought the comet, we must seal the weapons of the gods back where they lay or face the consequences!" midturn vote...
Its a favorite trick of quacks to proclaim vague dooms. Because bad shit happens all the time, so theres always something to pair to an omen
Noting we can stockpile without heeding the omen, but it ALSO means anyone babbling is a legit omen in the future.We have nothing to lose from stockpiling resources just in case. If we're wrong it becomes a reserve. If we are right we get much needed stability. The mine will still be possible next turn. Academia Nut's foreshadowing is pretty reliable.
Which with Observance is going to be a pain. Mad prophets are bad enough without feeding their mythos
