Regarding Asana’s Field Spells, they’re apparently referencing The Peach Blossom Spring, a Brigadoon-esque tale in China of a village that had long since cut off connections with the real world, and that is visited for only a short while before impossible to return to.
Konami naturally did their usual name fiddling, changing it from 桃源郷 (Town at the Source of the Peaches) to 透幻郷 (The Town of Transparent Phantoms/Illusions), a reference likely to the fact a large number of Wyrms (幻竜), especially earlier ones, in Yu-Gi-Oh! tend to be half transparent, like a specter or illusion or mirage, while also usually drawing from legendary and mythic dragons. This dual joke, so to speak, has to do with the fact 幻 means not only Phantom/Illusion, but it’s also usually the word of preference and choice in Japanese to refer to something legendary or mythic (such as the Egyptian Gods and Sacred Beasts in Japan), a good example being 幻獣, which is one of the terms you can refer to say, Chimera and Pegasus to.
Also to note, however, 桃源郷 and 桃源 are often used to refer to the idea of paradises such as Arcadia, Eden, Shangri-La, et al. Hence I will be sticking with that name choice.
