You type the code 28104 into the keypad on the lockbox and pull the handle. The lockbox door swings open, and you feel a spark of hope. Inside you find a severely tarnished brass key that looks like a perfect fit for the door on the wall. It has a piece of paper attached to the back of it with some sort of riddle upon it.

​

You move gingerly towards the door, keeping an eye on the sword and hoping fervently it won’t fall. You look down at the door, hoping to use the key to leave, and you immediately notice the door also has a keypad, which means you will also need some sort of code. Frustrated with another delay, you return to the lockbox, and sure enough, underneath where the key had been lying are two small sheets of paper. You sigh - apparently there is yet another puzzle to solve before you can be done with this place.

​

You examine the sheets. Again, you find yourself with an empty grid, this time measuring 6x24. There is also a smaller grid (3x8) filled with red and blue letters and punctuation marks. You devoutly hope this is your last test.
