Riddle Number Four

Time for a more challenging encryption, seeing how riddle #3 was decrypted so easily. First, I must note that this encryption was inspired during a chess match I partook in. I call it the ENIGMA CIPHER, a more notable cipher for those of the old Opord Analytical community.

Now, the riddle below is encrypted, as mentioned before. To solve this riddle, you must decrypt the riddle and solve it correctly. I will note that this will NOT be an easy task, but if it stays unsolved for a while, I’ll add a bounty.

Good luck to all.
