There are likely limitations of his powers. The Author could possibly write another Author into existence, but the Sorcerer will likely get mad and take the quill away and fix the problem. The author can pretty much reality warp with the pen to some degree. I will say either reality warp or just super strong magic.

The main thing about it though is the quill is made from an enchanted tree which doesn't see massively powerful. The ink does something. The paper isn't a necessity. So, together the quill and ink can literally do anything as long as the Sorcerer doesn't interfere.
