There were hidden spots and outposts at levels 3 and 4.5.
A standard, somewhat dimwitted human, represented by Vitya, on day 6 of week 2, reached Dragon Utopia for the first time, finished half of the treasure zone before the end of week 3, and then was defeated near a Castle; he ran to GO, where, according to my calculations, there should have been a Necromancer, and indeed, one was there. I reinforced his army and killed him; his stats were significantly higher (attack 31).
Thank you for the game.
