The message is encrypted using the Vigenere Cipher method.
The Vigenère cipher decrypts each letter by subtracting the key letter's position in the alphabet from the message letter's position. If the result is negative, we wrap around the alphabet.
| A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z |

Now subtract the key's position from the message's position. Repeating the key to match the length.
- If the result is negative, add 26

Our decoded value is: IAMONENTRALLA
Add spaces in between the words and it becomes: I AM ON ENTRALLA
The Entralla Route was a hyperspace that connected
Ord Mantell with Muunilinst.
- The missing operative is on Ord Mantell
