Questions:
do we know for sure that the order has the code?
do we know that the BHG are using the Z21 gate to get to alaska? why not the jump holes?
However, jump holes in alaska makes sense, or why would you have nomads in there?
And about guarding it, why not ad some small patrols? If why can't smack up some battleships at the gate.
And for anyone who would want it closed, what would be the good RP reason? And I'd like to know where we are going to put the prisoners and the experimental shipyard?
