Quests are objectives you complete by producing certain goods, achieving certain conditions, perform certain tasks, etc. The rewards can consist of coins, supplies, goods, military units, forge point packages, blueprints and sometimes diamonds. Story quests provide an overarching plot for an entire era. Side quests and recurring quests may be given by non-player-characters, depending on progress in the tech tree or on the continent map. There are sometimes event quests that when completing entire chain provide a special item.
