Orders are specific tasks given by the Crown, offering Reputation and other valuable rewards upon completion. You'll typically receive a selection of three orders at regular intervals. Choose wisely, as some orders might be easier to complete given your current resources and available blueprints, while others might push you towards new production chains.
Prioritize orders that align with your current production capabilities or those that offer significant Reputation boosts. Completing orders is one of the primary ways to gain Reputation, so always keep an eye on your progress. Don't be afraid to abandon an order if it becomes unfeasible, though there's usually a small penalty.
