"At inception, diplomatic missions were temporary in nature. As empires and trade expanded, permanent embassies began to be established."
- The embassy unlocks access to wonders if you are in an alliance. Higher level embassies unlock the ability to upgrade a wonder's level. Your Emperor must have an embassy to begin construction of a wonder.
- While the embassy is upgrading, the embassy remains fully functional and can still be used for donations as well as switching which wonder is under construction.
- In order to begin construction of level 2 wonder tasks, the emperor must have a level 2 embassy. However, players can still contribute to level 2 wonder tasks with a level 1 embassy.
