Wonders of the world
The Temple of Artemis
If you have errected this world wonder, enemy spies will be half as succsessful in reporting to their masters.
The Colossus of Rhodes
The saboteurs sent by your foes will be only a half as successful in their mischief as before.
The Hanging Gardens of Babylon
These gardens allow your city to grow quickly even beyond 500 inhabitants.
The Lighthouse of Alexandria
Your troops and those of your allies will have their movement points magically recovered after entering the city.
The Mausoleum of Halicarnassus
The mausoleum makes the enemys money counterfeiters kind of clumsy in their skill.
The Great Pyramid of Giza
Here you can resurrect your dead generals and praetors at a fair price. You can pay either with salt crystals or with the life of one of your less fortunate citizens.
The Status of Zeus
With every Statue of Zeus that you have you get one more traveller hanging around your cities.
