Right-oh, you will have to excuse the confusion. As far as I can work out Tel'Mithrim translates as 'The Grey Ones' (which I know you use for 'The Grey Company') so I assumed that you were leaning towards the Grey Elves as your basis. Thats why I got confused when I discovered a whole different 'Grey Elven' language.I guess I was really just wondering whether you had developed a RP history of where the language had come from and whether you saw it as having any links the various elven groups of Tolkien's 'universe'. However, it was just from curiosity so its not really important - the language is pretty good on its own. (Just don't try writing anything that involves 'change'! That whole concept seems to be a bit absent from the language, unless I missed something?)
Anyway, I'm just being picky again. Amazing job by all involved.
