Hi Springchicken !
I thought there was just one topic for Amertis and then... I didn't notice this one
To open a new world, you have to put the right image on the right page (look at each page, there is a hint to choose the right image).
Then put the right password : if it's good, it shall burn.
And after, you may pass the amulet on your complete page (just click on it) : a new stone would be illuminated.
Click "down" to let the amulet come back up and... remember Myst ? Put your hand on the image which is moving.
From real world to virtual worlds = book.
To come back to the house frome worlds = amulet.
And remember too : a book don't ever open at the first page
