When the man had finished, he filled his pipe and took his comfortable time over a smoke. Then he pulled on his mittens, settled the ear-flaps of his cap firmly about his ears, and took the creek trail up the left fork. The dog was disappointed and yearned back toward the fire. This man did not know cold. Possibly all the generations of his ancestry had been ignorant of cold, of real cold, of cold one hundred and seven degrees below freezing-point. But the dog knew; all its ancestry knew, and it had inherited the knowledge. And it knew that it was not good to walk abroad in such fearful cold. It was the time to lie snug in a hole in the snow and wait for a curtain of cloud to be drawn across the face of outer space whence this cold came. On the other hand, there was no keen intimacy between the dog and the man. The one was the toil-slave of the other, and the only caresses it had ever received were the caresses of the whip-lash and of harsh and menacing throat-sounds that threatened the whip-lash. So the dog made no effort to communicate its apprehension to the man. It was not concerned in the welfare of the man; it was for its own sake that it yearned back toward the fire.
- Jack London, To Build A Fire (1908)

This page is to give a general description of weather conditions in the game’s setting to help the ST and Players during their scenes. The Berlin area has a humid continental climate with warm summers and no dry season. It is located around the 52 degree parallel north at the same latitude as Saskatoon, Sasakatchewan north of the continental United States. Much of the information below is taken from the Weatherspark website. Although based on very recent data, it should be approximate to real historical weather.

Temperature
Despite its northern location, Europe is warmed by the Gulf Stream. Berlin experiences a more mild temperature than Chicago, being both cooler in the summer and warmer in the winter. Over the course of a year, the temperature typically varies from 26°F to 78°F and is rarely below 15°F or above 88°F.

Daily High and Low Temperature

Historical Moon Phases
For ease of game, strict time keeping is not being done. However, there are historical moon phases online we can use to keep a general track if needed. We can use Calendar-12 as a resource.
