Good point. Grey Team was often way out of the way and behind enemy lines. Fair enough. I just thought because we are finding them we might get to use the prototypes on missions to discover more :P
I've read almost all of the books. Haven't read Silentium or Primordium and one other, Mortal Dictata I think. So I'm down with this plotline, I love me some Forerunner tech.
Variable I know he is :P I've had an avid interest in the character for my own name :P It's a shame there's been no more story about him since Wars though.
He avoided them as well as he could, but had run ins with them as well. He found himself more willing and able to work alongside the Jedi than the Sith however.
Though if I don't/can't use him I can think of something else
