All marvels take up three hexes. (Except for the massive meteorite crater which takes up four.) Every biome has a unique marvel, and water has a unique marvel. Once a Marvel is found, a quest begins for all players, which requires players to explore the map to find various items. The quest is separated into two parts, requiring the player to gather a single sample and then two (or more, corresponding to your game speed; marathon requires 9) additional samples. Once the quest is complete the player will gain a bonus. Unlike wonders, multiple civilizations may complete these quests. Different factions can complete the same marvel quest, as well.
