A thorned rose that never blooms, A legendary key no lock to open. Cities of buildings without any rooms, A calm, still and waveless ocean.

I represent guide, but I am not a person. People think of me as the north one.

I resemble a book, but I do not contain a narrative. You can explore with me.

If you throw a black stone into the Red Sea, what does it become?

I always run, but never walk. I have a mouth, but cannot talk. I have a bed, but never sleep. What am I?
