The Binary Bard is revealed as Mordred. He disguises himself as the Princess and tricks you into giving him the weapons you have found. Then he disappears behind a doorway and you must solve a puzzle to follow him into the final room.
To solve the puzzle, you have to press 10 of the panels exactly once each. They are arranged in 5 rows of four cards each. The easiest way is to press each card in the 2nd row exactly once (1,2,3,4 or any order). Then press only the middle two cards of the 3rd row. Then press each card in the 4th row. (for a numbered version see below)
-----------------
The puzzle door is made of twenty panels; 4 in each row, and 5 rows. Numbered from upper left they are:
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16
17 18 19 20
Press the panels in this order: 5, 6, 7, 8, 10, 11, 13, 14, 15, 16. As long as you press each one of the cards in the 2nd and 4th rows, and the middle ones of the 3rd row, the result is the same.
