Apocryphauna

You have been sent to a private boarding school to be fixed. Your entire collection of Apocryphauna trading cards was confiscated when you arrived. Rebuilding it means operating carefully — if you are caught again, the consequences will be significantly worse. The nuns believe the cards are dangerous: that playing with them can summon Discordia, the mother of all demons. That cannot actually be true. It is just a game. Probably.
