Ninfia or Nympheon is the first of two Eevee evolutions to be introduced in Pokemon X and Y. Much like Umbreon in Gen II was one of the first known Dark type pokemon, Nympheon of Gen VI is one of the first Light type pokemon. Much like the Dark, Pyschic, Fighting and the Grass, Water, Fire trinities, Light pokemon complete a trinity with Dragon and Steel types. As when Magnemite and Magneton retroactively had Steel added to their types, most of the Fairy egg group will have Light added as a secondary type, such as Chansey, Audino, and Clefairy.
Thanks to Tinsares for digging into the official pokemon X and Y website source code for this. http://thedailyhotness.net/post/42939398704/ninfia-or-nympheon-is-the-first-of-two-eevee
I'm not sure if someone is wishing really hard with a photoshopped scan or not....
Well, unfortunately it's not. The image doesn't come from the "source code" or whatever, it came from a magazine, which we already knew (http://www.serebii.net/corocoro213.jpg). Furthermore, the "translation" given at the top of the page isn't what the page says. You can even see the little "???" on the image he posted where it says in the stats that the type is ???.
It's almost certainly fake. The source is "lol thx to my bro for digging through pokemon.com's source code" which the lamest excuse for a source I've ever seen.
First off why would pokemon.com have this type of information hard coded into a web page? It wouldn't, it would be a database entry which the site would query for. And why would they include source that isn't actually getting used? It doesn't make any sense.
