The Scrivenator 7

A large poster can be found on a board in the city of Equinox in the Feywild.

"Do you tire of constantly having to remember how to draw letters in order to send messages? Do you look at telepaths and think their real talent is never having to pick up a quill? Are your clothes too stylish to risk getting messy ink splattered all over them? Do you find writing boring?
Then the enchanters over at Nebble's Non-Stationary Stationery have exactly what you need. Meet the Scrivenator 7! Whatever you think, it writes. Floating by your side, this stylish feathered quill can take dictations, jot down your thoughts and even finish those letters you can't be bothered to wrap up. That's right, it can make predictions past writing as to what you should say! 
No parchment handy for a quick scroll while you stroll? No problem, the Scrivenator summons parchment on demand to ensure you are never stuck with a thought you can't commit to paper right then and there.
With prices to kill for, a range of feathers and plumage to choose from, and different ink colours, there's no reason not to come down to Nebble's Non-Stationary Stationery today!
The Scrivenator 7. Writing is a useless skill anyway."

Beneath the poster a few people have pinned some reviews of this Scrivenator.

"I can't recommend this tool enough, it's exactly what I wanted. I'd give it 4 of the 5 stars of the Caelur constellation."

"This is awful. I fell asleep with it still active and when I woke up there was a stack of parchment covered in everything I said in my sleep. It had kept summoning parchment to write and I got a huge bill for it! 1 of 7 stars of the Scorpion constellation."

"Do not get this. I let it make predictions for my letters to colleagues, and it used predictions from what I'd written about them in my diary! Let's just say it was less than flattering, and this screwy scrivenator copied it almost verbatim into the end of a business letter! No stars, of any constellation, just a black void of sky."
