Imperian has hundreds of help files to help you learn more about the game and how to play.
By typing ALLY <player> you may officially add someone to your list of allies. ALLIES will list who your official allies are, and UNALLY <player> will remove a player from that list. You may have, at most, 20 officially declared allies. If you wish to unally all of your allies at once, simply do UNALLY ALL. The significance of official allies lies in the way some abilities work and in the way your loyal mobiles, and other mobiles, will treat your allies. We will leave it up to the individual player to discover the particulars of this, however. See also: HELP ENEMIES
