First you have to get a 'create a hero' to defend your fortress, then you should build and archery range then build a few resource farms in your territory and then build 2 archers and a barracks by now you should be being attacked defend with them until 1 group of archers die then build 2 soldiers and 1tower guard then buil 1 archer and wait for your recourses to come back keep doing this and eventually you should have a huge army. Now upgrade them with armour and everything. DONT ATTACK YET!!!!!! Attack when your enemy has the least men possoible then press the 'a' key ad left click just behind the enemy fortress, your army should kill anything in it's path to get to that point.... Easy or what?
When you have to go to Dxun for the second time, you eventually get into a temple. Once in the temple, go down the pathway leading to the right (the right on your map), and you will reach a terminal called the "ancient terminal". You will need to solve an equation to open the "ancient box" that lies next to you. The terminal gives you this equation: (6 _ 2) _ 8 _ 9 _ 1 = 13
Here is the answer: (you will need to fill in the missing parts) (6 * 2) - 8 + 9 * 1 = 13
