When you write in this letter, the writing is logged into the letter. You can use an action to release the letter, allowing it to fly to any location or person of your choice within 5 miles. When the letter arrives at the location, it speaks out in your voice whatever you wrote in the letter, and then erases anything you wrote, and drops to the ground. The next time somebody writes in the letter, it returns to you, even if the writer requested it to go somewhere else.
