A4. It's like the Aran paper box event, stay online for 1 hour and you trade in the
item to Cassandra to get a paper box except there are 2 different boxes this time; Evan's Paper box and Onyx Dragon's Treasure Box. To get the Treasure box, you must collect 7 unique pieces (Which are also tradeable which means they can be bought and/or sold) from the Paper box to acquire a Treasure box. Of course, the Dragon's Treasure box gives better rewards, the Paper box only giving the 7 unique pieces or a Candy Twirl.
