Sapphires are rare and powerful gems that can be utilised to build fortresses and cities without using other resources. They can be obtained randomly by strengthening your fortifications and economy.

Sapphires can be used instead of the usual resources in every step of the fortress or city construction. Since sapphires are rare and valuable, the amount that has to be payed to complete the action is much smaller than the amount of resources that would be needed instead of a sapphire.
