This story is a sequel to Putting on a Silver Robe and Wizard Hat
Older, yes. Wiser, perhaps? If he had learned anything, he wouldn't be there. Offered a new chance to visit Equestria, he takes it, not understanding just how much it has changed since the first time. At least he lacks wings or a horn.
The prequel is not required or even suggested. This is a new story in a new world. It is only by the magic of authorship that one of the characters happens to be the same, but even they have been through quite a bit that was never written about. Come on in fresh, it's quite alright.
Being written for a lovely patron of my patreon. Scheduled at the start for 2 updates a month.
