I guessed the center correctly, although the entrance to the treasure zone was at the far end, but I reached it by the end of the second week; spent 3-4 days in the treasure zone, grabbed a staff and cloak-2-2, two max Dragon Utopias, and then headed to the enemy. At first, we fought for 4 weeks in the Castle; Rutger even surpassed me in levels, but the artifacts and Necro meat decided it.
Thanks for the game.
