In Chronicles of Merlin players are divided into three competing Kingdoms：Caesar, King Arthur, and Charlemagne. After you defeat the Baldwin IV of Jerusalem Chapter in the Campaign you must pledge your loyalty to one of the three Kings. Once you have made your choice there is no possibility of changing your allegiance. Alliances are also made up of members within the same Kingdom.

Title
Your Title is determined by your Prestige. The more Prestige you have the higher your Title will be. Your Title will also give you a fixed Salary which you may collect once a day. Upgrading your Title will also allow you to recruit more Heroes and increase the number of Farms that you can occupy. A list of what unlocks at which level of prestige can be found here.

Prestige
Increase your Prestige by attacking enemy players, participating in Region Battles or investing in your Region. You can invest in your Region once every 3 hours which also increases the Region's Prosperity. 

Gain Prestige, the Fighting Way
You're going to have to leave the comforts of your castle and go smack someone. You can do this by joining Regional Battles that happen every Autumn in Level 60+ Cities, or you can go into the world interface, and enter an enemy city and lay the hurt down all by yourself. 

Just keep this in mind:
Pay attention to the color of the players’ names on their castles, as you can gain different amounts of prestige depending on their color. The order of these colors is as follows: Gray(Friendly), White (Neutral), Green (Unfriendly), Blue (Hostile), Purple (Wanted), Orange (Most Wanted), Red (Enemy of the State). Also players of different levels offer different amounts of Prestige.

What Prestige can do for you!
Prestige can do a lot more for you than help you with this event. Prestige is used to unlock higher titles, which unlock lots of goodies. One of which is a salary, which increases with Title. Another is special heroes that can only be unlocked by raising your title.
