Weather

Eventually weather tables for each region may be developed, but for now the following system is used.

Procedure

  1. At the start of the expedition, check starting weather by rolling d6 to determine the starting column, and a d20 for the row.1)
  2. At every subsequent dawn and dusk, roll a d20 for the current column. The result may cause a change of column, as seen below.
d20 Clear (1-3) Cloudy (4-5) Precipitation (6)
1-2 Re-roll. If 1-2, go to Storms table. Re-roll. If 1-2, to go Storms table. Re-roll. If 1-2, go to Storms table.
3-5 Excess heat ← Clear ← Cloudy
6-8 Clear Cloudy ← Cloudy
9-11 Clear Cloudy Light rain
12-14 Clear Cloudy Light rain
15-17 Clear Cloudy Hard rain
18-20 Cloudy → Rain (d2 for light or hard) → Hard rain

In the winter, rain will be sleet/snow.
