Queen – “The King’s Sunset” [Campaign 1, Mission 5]

1) Alan! My map is all blue! In the middle, I see some yellow stuff, and to the right of it, there's a pale blue circle. What does the circle or the yellow thing in the middle of the map signify? And what's with the magnifying glass? How do I use it? 2) Jomalunga! What if I access this level through the campaign? Just point out the location directly on the black background (even approximately) - I'll figure it out, please.
