(Q - Gundim: I am currently asking myself the question, what are the sentinels? You had already told us a few months ago now that the sentinels are accessible 24 hours a day, 7 days
out of 7 and that they are in a public place. Would you say the same for all of the landmarks to be used in the last two puzzles?)
.
MB: The last two…, yes.
(Q - Gundim: 650 and 520, i.e. beyond the sentinels.)
MB: We know that in our geographical location, there are landmarks to find. There is surely a trick behind it that I don't see, since I don't know all the details of your solutions, but a priori, no, all the elements we need are accessible 7 a week, 24-24.
