Aldaleon's profile page is not the right place to discuss this, but I will reply here so that you would see it.
I have reviewed and rejected your proposed contributions. Though while doing so, I pressed enter too soon by mistake. About your "fëran = void" proposal, I was saying that neologisms are not made up out of thin air, instead they are based on attested roots and cognates, and your proposal does not have any such support. I am not sure what you mean by "real" but "fëran" is certainly not an attested (i.e. created by Tolkien, or simply "real") word.
I should add that "ë" is not used between two consonants in Tolkien's Quenya orthography, it should simply be "feran" (the word is still "fake" however). Your name is also using it, but Quenya does not allow "ei" as a diphthong either.
