Horology in Detail

Aschevon, the planet where the Parliament of Hours roleplay is set, is actually a moon that orbits the planet of Auswilder, which itself has an orbital period (circling the nearest star, He’en) of 300 days, meaning that one Aschevon year is also 300 days. These days are split into ten seasons, each of thirty days. The seasons are typically announced by a change of weather, including rises or falls in temperature, and the cycles of Auswilder’s second moon, Aishor – Aishor completes one orbit around Auswilder every thirty days, meaning that the length of a season and a month are one and the same. Aschevon and Auswilder, however, are tidally locked, meaning that people on one side of the planet – including everyone featured in the roleplay – will never have seen Auswilder, and will be unaware of its existence.

It is widely accepted that there are thirty hours in a day, based around the continental countries experiencing approximately 15 hours of light and 15 hours of darkness throughout the quarters of the seasons. This balance can be thrown as one travels further north or south on the planet – hours of light and darkness vary immensely throughout the year closer to either planetary pole. Aschevon takes approximately thirty hours to orbit Auswilder once, and thirty hours to rotate on its axis.


Aschevon experiences roughly ten seasons, divided into two archseasons – Summer (warm) and Winter (cold), with varying amounts of precipitation throughout the two. Regional and cultural variations in the taxonomy and definition of these months exist, but the seasons are also numbered from one to ten, in order to keep dates consistent between various cultures who experience the seasons slightly differently. In Montmarais, the seasons are referred to as following:

  • 1: Temperate Season: The temperature is cool and mild.
  • 2: Warm Season: The temperature slowly increases, resulting in a warm or hot atmosphere, with semi-frequent precipitation.
  • 3: Muggy Season: The temperature continues increasing, and sudden rainstorms are frequent; nights are often “muggy” – hot and humid.
  • 4: Dry Season: The rainstorms peter out, resulting in a period of very hot weather with little precipitation.
  • 5: The Winterusher Windy Season: The heat becomes displaced by cool breezes, leading to thunderstorms.
  • 6: Misty Season: Precipitation slowly returns, resulting in a mild temperature, and the windy season dies down, resulting in settled mist (or, in the industrial parts of the city, heavy smog).
  • 7: Rainy Season: Precipitation is at its highest point in the year during this season, and the temperature begins to drop.
  • 8: Flood Season: The near-constant rain of the former season results in the flooding of the Fens, and the rivers in Montmarais. The temperature continues to drop.
  • 9: Snow Season: The temperature is at its lowest at the beginning of this season, but slowly increases. It is not uncommon for the season to be heralded by the freezing of parts of the rivers, and snowfall is possible, although not always present.
  • 10: The Summerusher Windy Season: warm breezes begin to melt the ice and snow of Winter, paving the way towards Summer.


The State Isles, and the countries that trade heavily with them, utilise a calendar known as “the Sauhister System”, developed by Lotte Sauhister. Legends claim that she unearthed a diary kept by some unknown culture, and was inspired to chart a globally-recognised system that would ensure that all cultures would be recorded throughout history.

Sauhister’s original system had a starting date based on the birthday of her grandfather at some point during the snowy season. However, she posited the system to a coalition of tradesmen from various State Isles and, in order to simplify the system and ensure its propagation, agreed to make “Year Zero” the one they were presently in, starting from the Temperate season, which was a few weeks away. The tradesmen agreed, and the calendar was passed on and standardised throughout the State Isles – and from there, other nations began to utilise the Sauhister system.

The Sauhister is standardised at “Year Zero”, which was the night that Lotte Sauhister introduced her idea to the sea-merchants of the State Isles. Events that occured before that date are considered “prehistory” – however, if fairly accurate dates can be given, they are designated by the number of years prior to Year Zero, then the last letter of the culture’s alphabet; for example, an event occuring 300 years before Year Zero would be written 300Z. All other years are written with the first letter of the culture’s alphabet, then the number of years that has elapsed since Year Zero; so, the year of the termination of the Breqaer-Mrosrajy war would be written A612.
