"Yes", Adrien said, showing the envelope. "Could I ask you to send it?".
"Of course", Valerion said. He waved his hand around; the letter slipped out of Adrien's hands and floated towards one of the bookshelves. A wooden box located on the bottom level suddenly flipped its lid open and the letter fell inside, making no sound; then the box closed itself shut. Adrien turned towards Valerion with his mouth open, speechless.
"The box contains a portal to the post office in the village", Valerion said with a smile. "It took me a while to convince them, but eventually they understood that dealing with a little bit of magic was undoubtedly the better option compared to having to send their people all the way up here. They made me sign a lot of waivers, though", he added with a chuckle.
Adrien grinned. "That's amazing", he commented.
"Isn't it?", Valerion said with a smile. "Ah -- you still want the scrambled eggs?".
"Oh! -- yes, please. Thank you".
