Karen there are easier things to do than that harmonic puzzle. If you have already done it once, you can test various compotes on Michel, just be sure to have a glass of water handy to reverse effects. You can go in and out of the Necropolis door at least three, maybe four times and rack up your lunar intelligence. So many ways to increase lunar intelligence unless you just liked that harmonic puzzle.
Yesterday is but today's memory, tomorrow is today's dream.
