This is actually possible. Just watch the video I made.? It is in German. If you have a problem with that just let me know. Or you just download the template I made:? http://www.file-upload.net/download-11823230/200x200template.map.html There you have a cede castle event to get the castle after killing all enemy troops in it. The time on/off events prevent the time from running, so that you cannot be attacked by enemy forces before even owning the castle. By the way: The Auto Binks On/Off-Events prevents the game from warning you before an invasion. This is quite useful if you don't want to make a storyline for your map, that does not contain one of the four classic enemies, e.g. the rat.
