i posted an annoying unsupported thought on my own, but my neurosis forces me to reply here with my silly theory in mind:

"Hey Matt, you can enter the ToG via a doorframe Terangreal located in Caemlyn's palace where this pantry used to be. I know you've entered Finnland before but this is a new door so you can go back again b/c that rule was only bound to the specific doorframe you entered through originally. I suggest you go this way b/c the Finns are only bound to the ancient pact when you use a doorframe."

and if that isnt crazy enough for you how about:

"P.S. Be careful, Asmo was killed going through that door by INSERT SUSPECT HERE [Slayer/Lanfear/Moiraine] and as it turns out, if you die there you are dead for good. so be careful, cupcake!"

or even more out-there and not worthy of respect:

"P.P.S. Take Birgitte--you see, ToG is actually part of TAR and as she was ripped out bodily, she can be made whole and also find Gaidal."
