In my RPG Swords of The North, i'm going to be needing one of these.
What i'm asking for, if anyone remembers, is you have warmth, which sort of acts like hunger, and depletes when not near a warmth brick. Standing next to a warmth brick will heat you back up. For a v21 edition, i was wondering if when you were below 1/2 warmth if a white vignette would appear. If you run out of warmth, you die.
