Not sure if this is a bug or just some really ambiguous phrasing, but it says that the spelling and pronunciation of Lalafellin names is due to them only have 5 vowels (a, e, i, o, u.) Except I'm pretty sure that the other races have the same amount of vowels as well, it wouldn't make sense unless their old language had no consonants.

Is this a bug? does the old Lalafell tongue have only 5 letters?
