If you need any phrases or setences of languages for roleplaying or something, I could create a skeleton frame of a language. I have an interest and knowledge of linguists. Making languages is a sort of pet project of mine.
I was thinking Dark Dwarven or Fairy. I'm not Tolkien, but I'll give it a try. You'll have to tell me what kind of sound and style you would want for a language first. But how would I get the work to you, the forums?
Dark Dwarven would be similar to dwarven-- same roots-- and Fairy to elven. Both are Tolkienesque in my world. If you take a look at the site and make them match the existing stuff I have up about those language, you can do either.
