According to the rules, merchants can only be placed in open regions, meaning that opportunity would never come into play in this case. To place a merchant in a closed region, you would have to spend a special envoy which also negates opportunity. Is this correct?
"5.2.5 Special Envoys. Players may spend a single special envoy to ignore the opportunity requirement during the place action OR to place a merchant (from your holdings) in a legal zone in a closed region. The spent counter should be returned to the player’s stock."
The way i read it was the Special Envoy can be used to do only one of special abilities:
A) ignore opportunity during a place action
B) place a merchant from holdings in a legal zone in a closed region.
