I drew a central figure and I improvised around it. The calendar have 6 months of different length: 14, 24,29, 31, 41 and 46 days. A year is two cycles of these 6 months, the first cycle is named the young one and the second the old one. So for exemple you have the 5th of the Young Cold Star and the 5th of the Old Cold Star.
The six months are represented in the vertical bar of the calendar: The Cold Star that freeze the land and crack the stones, the Breaking Stones who shake the land but free the warm iron, the Ember Steel who warm the hands but who wound the people, the Storm Tears who unleash passions but who make things grow, the Mother Grail who collect the tears and transform them into something new, the Born Fire who is full of life but short lived.
- The two women heads represent the warm sun and her lover, the cold sun who was born like a boy but grew like a woman.
- The two moons represent their dreaming selfs, one his cracked and bad dreams often escape from it.
- The small star represent the cold star, a white dwarf that gravitate further away from the two lovers and who often try to separate them, she is often represented as a undead crone.
I drew different icons that represent special events that are celebrated during the months.
More world building can be generated by defining the events that they represents.
Maybe we can use a random table for inspiration, the day is a celebration of a (d10):
- natural cycle
- unnatural cycle
- historical event
- mythological event
- popular festival
- ancient ritual
- human activity
- holy day
- rite of passage or union
- roll twice and combine the results
I like how crafting the calendar craft a cosmogony, I think there is a lot of space for experimentation when drawing calendars like maps.
