+
+     • aaaaa-bbb-z-y-x-123[abxyz] is a real room because the most common
+       letters are a (5), b (3), and then a tie between x, y, and z, which are
+       listed alphabetically.
+
+     • a-b-c-d-e-f-g-h-987[abcde] is a real room because although the letters
+       are all tied (1 of each), the first five are listed alphabetically.

-   The room names are encrypted by a state-of-the-art shift cipher, which is nearly unbreakable

-   To decrypt a room name, rotate each letter forward through the alphabet a number of times
-   equal to the room's sector ID. A becomes B, B becomes C, Z becomes A, and so on. Dashes become
