Ancient Crystals

Gray area, I'd houserule that you have the ancient crystal harvesting available from card 4 onward. The game is quite experimental, so it's not that important whatever someone decides.

Ancient Crystal pairs (item):

LCD Aug (TLH #4) the card itself is clear enough (at least one hero must succeed at both, and True Solo rolls twice).

But it is unclear whether or not it allows you to harvest crystals from TLH #5 onward – i.e. while you are developing this saga. The card doesn’t restrict usage to #4. The crystals are still on the map. It makes sense that once you know of their use they are available in future plays while you develop this saga, plus in TLH #6 (LCD Nov)they are mentioned as well. If you allow it, keep this card on top which allows you to attempt to harvest this item. May have some effect: vs the Magi.
