AGOT : Seasons of Ice and Fire

A Lore-Friendly Submod for CK3 AGOT that implements the infamously variable seasons in ASOIAF. With the seasons ranging from months to years, with their lengths being weighted according to historical season lengths according to the Lore. Seasons of Ice and Fire aims to bring the important aspect of seasons to your CK3 AGOT experience, allowing for strategic planning around the variable seasons, experiencing lore-friendly events and providing deeper immersion into the world of Ice and Fire.

Additionally, the map now reflects the season and its weather, meaning during winter, appropriate regions will experience snow fall, and the map will be blanketed in snow during the winter years. During the summer, it can be a drought, or flourishing, and the map will reflect that.


- New Situation for the Seasons
- Each phase corresponds to a season
- Variations for each season, corresponding to temperature (hot, cool, temperate), and humidity, (dry, wet, etc), or region (Northern Winter, Southern Winters)

- Variable attrition rates for each season
- A number of different modifiers for each season to reflect changes in season, increased income from harvest, etc.

- Regional Variation, winters in the South will be tame compared to the North, and each of the major regions will experience a slightly different season, however they often correlate with their neighboring regions for a more natural feel.
- With almost 50 Subregions currently in place, and each season having numerous variants, each season will be unique!

Seasons of Ice and Fire mimics the impacts of the seasons in ASOIAF, with summer being the time of growth and abundance, the game will provide boosts to fertility, health, taxes, various opinion modifiers, development growth, lower attrition in regions where appropriate (Such as Forests, snowy areas, etc) and higher attrition where appropriate (Deserts, Jungles, etc), men at arms and levy reinforcements. Construction and development are the cheapest and easiest in the Summer.

With Autumn being the harvest, and the final stretch before winter it's geared to encourage you to build up a stockpile and prepare for the incoming winter which could last for years, attrition is lower in Autumn, and supply lasts a bit longer, and as such it would be wise to end wars before winter arrives, and thus avoiding a long drawn out war of attrition.

During winter your income will be severely reduced, and often running a deficit if you don't cut back on expenses, armies will cost considerably more, and attrition will be significantly higher where appropriate, the AI will be more inclined to accept a white peace and significantly less likely to go to war during winter. If you find yourself stuck in a war during winter, you will find that it is to your advantage to stay on the defensive. Additionally there are penalties to fertility (may be adjusted) and health, as bringing a child into the world during winter would be a strain on resources, and health suffers during the cold. Construction and development will suffer, after all finding laborers in the winter may be more difficult. With everyone in closer quarters at home stuck inside from the cold, schemes and family relationships will be boosted, and in many cases crime (control increase) will be reduced (As a balance to all of the negatives, may be adjusted).

And once the Winds of Winter have passed, the Dream of Spring will be here, attrition is overall lowest in Spring, except for wet environments (Swamps, Floodplains, etc), and there are considerable boosts to fertility and health in Spring, balancing out the Winter. Spring is the season of recovery, when things are the most balanced as coast into the prosperous summer.


By using the Situation Mechanic the mod is able to simulate the variable season lengths and significance of the World of Ice and Fire. An event with a timer is set to fire for a variable amount of time, and when it triggers it switches the phase of the situation to the appropriate season, along with adding a modifier for all characters for small impacts on health and fertility depending on the season.

**This mod is in Beta, and I originally created it purely for my own enjoyment, but figured others may as well. Please let me know if there are any errors or if anything is not functioning properly.


I recommend loading Seasons of Ice and Fire either at the bottom of your load order, or as close to it as you can. It can still work higher up, but some features may not be fully functional.


Seasons of Ice and Fire should theoretically be compatible with most AGOT sub-mods (if not all mods.)
The mod currently modifies only a few vanilla files, however they are not strictly needed, but are still important. See details of files changed below.

Is it Save File Compatible? :
Yes and No. You can load it into your save, but you need to activate it manually. You'll need to trigger the situation , and the spring season events using console commands. ( effect = {
start_situation = {
type = agot_seasons
start_phase = seasons_spring_phase
} and then event season_events.002 . And that should work. It is possible to activate historical seasons on a save file, but it would be tedious, you'd need to find the closest date for a season switch in the events file, and trigger that event instead of season_events.002, see Non Supported Start Dates instructions for a better explanation.

Non Supported Start Dates
If you are playing with a non supported start date, but want to use historical seasons, you'll need to trigger it manually, or change the files to support start date. See pinned guide below for detailed instructions.

Other Mods
For map expansion mods, see the pinned guide on adding new regions below.

Multiplayer?

Yes! Seasons of Ice and Fire Will work with Multiplayer
