Out of curiosity I tried to put some of the mistiness back into the contrasty version - over done and no local area type lighting changes.
Reduced colouration and contrast but a large part of the effect was simply dragging the white end of the curve down leaving a straight line. Not much either.
Then taking that I made a slight change to the gamma using the centre pointer in levels. Mid tone contrast changes after a fashion. Gamma redistributes the bits allocated for each EV in the shot. Curves does too but levels can be easier to use.
What I am sort of saying when converting raw go for the best possible image 1st and add the look if wanted later. All sorts of things can be done to image if it's basically sound. Saturation, contrast and curves setting could easily enhance mist as the first shot shows and they all inter react after a fashion and if a too contrasty colourful image emerges from raw it can be changed later.
Colin threw in an interesting aspect of making further changes - leave room in the histogram for them if they are needed. Levels can make that aspect easier.

Having said this I have some misty shots that I can't cure - yet - so I am going to try selective sharpening as has been suggested not local contrast. Also in this case Christina's raw development may not have altered the outcome.

Some might notice a bit of banding in these 2 shots - it's really been through the mill so hardly surprising. Original --> high contrast --> soft again --> as I like it maybe. I feel a slightly soft sombre majestic looks suits it.

Others probably wont see it like that.
