Toby was very familiar with Staph the pixie and her proclamations. It was she who had first suggested that he “go home to grow his beard and fiddle with his pillar,” which was obviously a reference to his future as a wizard living in a properly terrifying tower. He had followed her suggestion immediately, and he still wasn’t done fiddling with his tower. He had many improvements to make, in fact, and assumed he’d be fiddling with his tower and grooming the shrubbery around it until he was a doddering old man and his tower was falling down.
