Just got Treason of Saruman.
The last heroes i used during TRD were Sam, Aragorn, and Gandalf.
I chose Sam as the captive, and Aragorn is now the Fellowship hero. That leaves 2 open hero slots if I keep Gandalf.
So, Will I get the threat penalty for selecting 2 new heroes when playing campaign rules, even though I've been somewhat forced to open up these 2 hero slots?
