Intrigue levels allow spies to get information on other empires. To get information about another empire, just use the "Spy on Empires" edict, select the empire you want info on, and select "Get Information".

Note that you cannot go below 0 intrigue and above 5 intrigue. A result of "-1" is negative income and a big number with a 1 at the end means the value is above that number. Also, the max intrigue between you and another empire can be decreased by 1 if you or the other empire closes borders to the other.

-Nothing. Try to get more intrigue by doing successful espionage missions.
