The trojan war.

You sit on a ship watching the city of troy. Those trojans have taken your wife. Your love. You feel outraged but you know that it is bad to hate people. You know that it will go well to do the right thing. Not because there is any reward but simply because you must. The other kings and queens of the aegean describe you as noble, scrupulous, well meaning, righteous, and virtuous. You brush these compliments aside by saying that you are just a normal guy but you cannot deny being righteous. Now, war is at hand. Whether or not you are excited about it you must fight. The war is starting. You are about to engage in a battle bigger than any you have experienced. You put on your armour and sharpen your axe. As the battle is about to start you think on what you should do. You could try to breach the gate or fight ferociously and skewer every trojan you see. You could also try to get over the wall with the one of the ladders.
