Thanks for the reply. So basically I'm correct and these are the only exceptions?
I think there's also a stack 4 card that moves cabs on the board. Yeah, the player picks a region (any region but the king's region) and all other players move their cabs from that region to any other region (again, except the king's region) selecting secretly with the disc.
The restriction on placing cabs into regions adjacent to the king is only on the number of cabs the action card allows you to move from your court to the provinces. The special action of the action cards each have their own particular set of rules.
The only "universal" rule on placing or moving cabs in El Grande is that nothing ever (never, ever) goes into or out of the King's region.
