Hello, everyone!
I have found Secret Room #006 in the second part of the forest and Secret Room #008 in the Graveyard pool! I have not found Secret Room #007, though! I have found all the previous ones, portal, northwest Azan, Council and two in the first part of the forest.
I think I have inspected the forest thoroughly before entering the Graveyard, square by square, and the Graveyard to the best of my ability before #008! So, where is this elusive #007?
