Correct me if I am wrong (and I am sure someone will....lol),
But I seem to recall Trollocs being gated in at some point, I do not recall if it was
Camelyn, or the Stone, or where, but I think I remember Trollocs coming through gateways and
attacking. This goes against the idea that shadowspawn going through gateways destroys them.
It is possible that this was an error that was corrected, or that I am just mis-remembering things.
Either way...
I am still looking forward to this book!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
