(Warhammer, but diceless) I have written a short story where my players (a small squad of soldiers) are venturing deeper and deeper into the north chasing their enemies. I want them to hate the winter, hate the climate and hate their sergeant more and more for not letting them start fires, not letting them sleep enough, having shivers, cold food and bleeding lips, I want the players (who are kinda new to RPG) to understand how their characters are feeling and delve into the story.
I'm looking for rules on how to describe winter and what happens with human minds and bodies if you go further and further north. I'd like the climate to sit on their psyche. Does something like that exist anywhere?
Thank you in advance.
