L-M2 Encounters
This have been quite a fun conversion work. In the M1 encounter I added some more descriptions on what the characters could see within the ice blocks, as well as I did a tweak of the haunt which will have players deciding either to take the challenge of staying to learn more, run away in terror, or leave in order to not face the damage dealt.
The M2 encounter with Thora Petska, the guardian doll, could become quite memorable as well. It is the first encounter in which they face the magic of the white witches, which should scare the party. In 4th edition I have made the guardian doll a solo monster (used a demilich and a beholder for inspiration). Will be fun to see five adventurers fighting of a single levitating doll!?!!
Please give any feedback on the doll, if you think it is over-powered or not.   
 As I am only copying the necessary game elements that should be used in  the 4th Edition game, I have taken away all the great context,  information, and stories which creates the 
magic of the Paizo  product. I therefore strongly advise you to purchase the Paizo products  this conversion have been built upon, to run the Reign of Winter  campaign. I did!
 You can buy them from 
www.paizo.com online store.
