The Positive: I like this! It's a solid, interesting idea with a lot of detail. I can see how it fits into and illuminates your world.
The Negative: The text is a bit verbose. If you're bringing your reader along on a lengthy ride, you should give more of a payoff along the way: Some sort of a twist or surprise would really add to the piece.
The Constructive: What amazing benefits might arise from Corran's Scribe? What awkward revelations might the scribe bring forth? Whose sinister designs might require just such an object? What tales might it best fit into?
