I remember its about a guy who can travel from our world to a magical world. The magical world calls ours the mundane, everyone there has some sort of power I believe. One woman could enchant everything around her so even though she was very old she looked young and beautiful her surroundings were always beautiful for as long as she kept up the illusion. I've been looking for this series for about 2 yrs now and have had no luck so any info anyone might have would be greatly appreciated!! Thanks :D

Could this be Scott Savage's "Far World" series, with "Far World: Water Keep"?

Piers Anthony wrote a series of books about a land called Xanth. It sounds like that's what you're talking about.
