Also the meeting in Vendreicce (sp) is supposed to be on the 20th of Winter, however they clearly start the meeting almost as soon as the train arrives. Is the plan changed due to the parties actions or did I miss something?
Hm? They only get sent back to the beginning if they fall off the train. Unless something was changed in the 5e version.I would advice you to deviate a bit from the Nem encounter as written. My players did not enjoy it. They found it frustrating having to make their way through the entire length of the train, getting very far only to be teleported back to the start whenever they got hit.
The GM Chose to have the enemies slide them off the train. Unless 4th ed is even less flexible than I thought. In PF i don't remember any special abilities which really encouraged me to do that to the players , and with anything in a scenario if it does not work for your players change it. Knocking someone of the train sounds like it may be interesting once or twice but no reason for the mindless undead to do it repeatedly.4e, the enemies slid them off the train. Particularly the last one I believe, the big wraith.
