As far as I can remember, this is what I did:
Summary
I prayed at the altar and got the fog globe.
I went to perdition and opened the globe.
I was in a room with a cave. I went into the cave. I saw a hill. I went on the hill.
I saw a house. I went into the house. The hints said there were drawings. I looked at the drawings. It was a picture of Anubis.
That’s all I found so far! I do not know what I ignored, it must have escaped my attention, and I’d be happy to know what it is so I can progress!
