If you are a member of an alliance, you can gain small amount of resources, gold and specialized items when complete alliance quest.
Here are some examples of the quest that I can usually complete all.
example of personal reward.
here is the Embassy building, where you can donate coins/ gems, exchange activity points, collect rewards and forum.
embassy building in the city. the building is available in each and every one of your cities.
when the alliance members reach a certain number of activities collectively, they can claim the rewards at the bottom. we can get a resource cart, hour glass (to shorten marching time), camp fatwas, ring of the fallen (to produce skeleton soldiers). the number is reset every week.
here we can exchange activity points. I click activities and send others activities, so hopefully others will click and give me activities back.
this is an example of ranking in the alliance. one's rank is higher when his activity is more. green shows your own rank stat.
this example shows members with no activities. when this happen, the leader and/ or ministers will urge you to at least reach a number of activities or face the cinsequences of being kicked out of the alliance. a general is the normal member. a minister can manage the alliance alongside the leader which is the owner of the alliance.
