Your picture is very blurry. Are you looking at the Transist (sp?) Hub? They are like Wayshrines in Cyrdodiil. You go to where the action is on the map or where you want to quest. Activate the Hub and then you can see where to go, based on the lines that are connected to other hubs.
Now, if this is your first time in Cyrodiil, you want to do the intro quests, you get a couple of skill points and learn how to use Siege equipment. Look for the quest arrows to find those NPCs.
