The Tenor

"The Tenor is a slang and contradiction jargon spoken by the residents of Labyrinth, the Nexus, and has spread like a babbled malady across the motley burgs of the Great Beyond. You should learn the stylish vogue in verbosity from 'The Maze', so that you won't 'look like a green tyro'. If that last bit didn't make sense to you, begin studying below! . . ." —Monty Kolh, scholar of linguistics
