The possibility of actually visiting an imaginary place seemed irresistible. In terms of my journey, not to go there would be a dereliction of duty, like saying ‘I could have made a detour to Rock Candy Mountain’ or ‘Tir-nan-Og’, ‘but I decided to press on directly to Maghull instead’. So today I decided to make the expedition – from the world we know to a fictitious and uncertain place.
