Sauron, The Little Notebook that sees all, knows all, smells all...

I'm part of a secret and well-hidden society who believes in the existence of Sauron, the little notebook who sees all, knows all, smells all.
I cannot provide you any further details, since Sauron appears only for the chosen ones.
And we are a group of four chosen people.
Please, don't get too curious about it. Any further questions shall not be answered.
