From this page, you may change several properties which govern your dominion.
If you find yourself in a situation where your dominion's current civilization prevents you from reaching a particular goal, you may, as a last resort, reform your civilization. Beware, however, that such a transformation will have serious side effects.
In order to carry out a civilization reform, you must have a sufficient number of Scholars, at least 100 commands, and your health must be at least 75%.
The upheaval caused by this reform will kill 10-15% of your population and military, destroy roughly 35% of your structures, and cause you to lose at least 15-45% of your stockpiles of Money, Grain, and Knowledge amidst the disorder. Finally, 100 commands will be consumed, and your health will be reduced by 50%.
Note that if you made a mistake while selecting your civilization during registration, you may perform this procedure for free if you have not yet used any commands.
Your tax rate determines not only the amount of money your dominion's population contributes to you, but also their happiness - low tax rates will encourage immigration, while high tax rates will drive your citizens away. Furthermore, raising your tax rate will reduce how far your dominion's Health will recover on its own.
If you have built Barracks on your land, you may use these settings to control what types of units they will produce. When resources are allocated equally between all unit types, Spearmen, War Elephants, Fire Ships, and Triremes will be produced in a 12:6:3:2 ratio.
Specifying percentages whose sum is less than 100% will cause your Barracks to run at partial capacity, which can be useful if your finances are temporarily unable to support additional troops.
If, for some reason, you are unable to login for an extended period of time, you may place your dominion on Vacation to protect it until you are able to return.
Once you choose to go on vacation, you will be locked out of your account; after 12 hours, your dominion will be frozen and no other dominions will be allowed to interact with you directly (though you will still share your troops with alliance members, and items already on the market will still be sold).
After your dominion has been locked for a minimum of 72 hours, you will be allowed to login and unlock your dominion at your own convenience, at which point you may resume normal gameplay. Do note that once the final week of gameplay for the current round has begun, your dominion will be automatically unlocked at the earliest opportunity (so as to prevent players from using vacation to protect their high rank).
