I believe the puzzle to be a Nihilist cipher as the cache title refers to a fictional German band and its album title. Grandpre. The Nihilist cipher is quite similar to the Vigenère cipher. Because each symbol in both plaintext and key is used as a whole number without any fractionation, the basic Nihilist cipher is little more than a numerical version of the Vigenère cipher, with multiple-digit numbers being the enciphered symbols instead of letters.

In the history of cryptography, the Nihilist cipher is a manually operated symmetric encryption cipher originally used by Russian Nihilists in the 1880s to organize terrorism against the tsarist regime. For a 5x5 grid, the 26-letter latin alphabet do not fit, choose a letter to omit, often the J, V or W are omitted. It replaces each plaintext pair of letters by another two letters, based on the four encryption tables. Multiple keys: it is possible to use several keys, summed successfully, but this only extends the process time and does not complicate a brute-force attack.
