While I thought that elves worshipping Gruumsh was kind of weird sounding at first, I have to say that I love this article and its implications for 4e. In particular, I liked the strengthening of the connection between elves and fey, and I especially liked how the eladrins of earlier editions have been incorporated into the 4e eladrin backstory. Personally, I have a feeling that the Celestial Paragons like Queen Morwel and her court will still exist, perhaps in the Feywild, but more likely in Arborea with Corellon either as demigods, advanced versions of the eladrin, or 30th level eldarins with specific epic destinies.
