During the first half of the Super Nintendo role-playing game Chrono Trigger, you will come across several sealed black boxes that don't appear to have any key with which to open them. Later on in the game, when you finally acquire the means to open these boxes, you will want to retrace your steps and get all of the high-powered items they contain. The White Mail Armor, which makes a character immune to specific magical attacks, is found inside a black box in the village called Porre.
