i never dismiss any small detail, im going to look more into this...reen must have been a remarkable person given that he never broke when the inquistors torchered him, and we know that kelsier thought Marsh, when he persumably found him lying dead on the floor, would have not been able to....so he is not a character to dismiss, and since he is supposedly dead this piece of obsidion is all thats left to consider...this is not coming out as clear as i would like...let me start again. ehm. Reen is a very important figure, or concious in Vin's head...he seems to have done what very few can(bearing the inquistors torcher) and by default we can assume he loved Vin though he never mentioned it once to her....he and his obsidion piece are no small detail...but i guess we will find out come the fourteenth of october! Umm, if you guys havent already, to kill time, and so you dont loose your minds waiting, here are a few books like, or as good as the Mistborn trilogy....enjoy!
The Name Of The Wind--Patrick Rothfuss
The Eye Of Heaven--David Keck
and for a more satirical approach, Goblin Quest--Jim C. Hines
