Sometimes you wrote Trevyn and sometimes Trevin. They are the same, right?
Trevin’s age comes up later in the book again and is given with over 800.
In that scene we learn that she’s over 1000 years and that the Nyjyr were driven out at that time. I think the second part is more important, but could easily included at other occasions.
Concerning the Alvaran-Modgriensofarthgonosefren animosity: Is it important to introduce it yet? Wouldn’t it be better to introduce it when you need it. Maybe in book 3? Do i get it right, when i say the Alvaran are Elves? Because in that case you change terminology at the end of the book.
For introducing the Prince and lesser Elraith lot: I can’t remember any of them. They didn’t do anything important (as far as i can tell). Again wouldn’t it be better to introduce them at a point, in which they do something or are involved in an event that’s in some way important/remarkable, so that it’s more likely to remember them? Maybe other readers see that differently.
