Builders' Hut - Can I use it to reduce the building costs of the Great Thingstead?

The “Age of Enlightenment” Expansion

City Palace - Can I reduce the building costs by means of a Building Crane, and if yes, can I also save a star?

Note: Michael the Master Builder belongs to the Age of Darkness expansion.

The “Age of Enlightenment” Expansion

No. You can look through the discard pile not a draw stack. But you only can take an action without requirements card or unit.

The “Age of Enlightenment” Expansion

The “Age of Enlightenment” Expansion

Yes - if you own at least one star on a Public Feeling card.

Common Land - Is the star-for-resource trade via Common Land a trade with the bank as described in the context of the Master Merchants' Alliance?

The “Age of Enlightenment” Expansion

No.

Note: The Master Merchants' Alliance belongs to the Age of Darkness expansion.

Court Astrologer - May I use the Grove of Vigilance against an event triggered by the Court Astrologer?

The “Age of Enlightenment” Expansion

No, the Grove of Vigilance may only be used against events rolled with the event die - not against events determined by the opponent.
