9. Custom Biome (If you have a biome in mind that does not fit one of these categories)
1. Resource dice: You may arrange your dice in any order you wish, such as by putting a 1d4 in animal products and a 1d8 in metal, using the following array- 1d8, 1d6, 1d6, 1d4, 0 (no resource). The DC for your water is equal to 15.

Category names are not equal to their numbers!

Category 1 (Hamlet)

• Category number: 3 
• Your settlement is a hamlet if it has 100 or less people. 
• Requires 3 of every resource to rank up
• Important building capacity: 3 
• Resource cap: 10 in every resource
• Food requirement: 3

Category 2 (Village) 

• Category number: 10 
• Your settlement is a village if it has 101-500 people.
• Requires 10 of every resource to rank up 
• Important building capacity: 6
• Resource cap: 50 in every resource
• Food requirement: 10

Category 3 (Town) 

• Category number: 20
• Your settlement is a town if it has 501-2,000 people.
• Requires 20 of every resource to rank up
• Important building capacity: 12
• Resource cap: 100 in every resource
• Food requirement: 20

Category 4 (City) 

• Category Number: 100
• Your settlement is a city if it has 2,001-10,000 people.
• Requires 100 of every resource to rank up 
• Important building capacity: 24
• Resource cap: 500 in every resource 
• Food requirement: 50

Category 5 (Metropolis) 

• Category Number: 500
• Your settlement is a metropolis if it has 10,001-100,000 people. 
• Important building capacity: 50
• Resource cap: 1,000 in every resource
• Food requirement: 100

Caps at 100,000 people. Must create a new settlement after that. 

You can create a new settlement (must be hamlet sized) using 10 of each resource and 10 people. 

Must spend resources to upgrade category. 

If you cannot meet the food requirement, your settlement goes down a category. 

Water simply works like if you create a civilization, you’d roll the d20 to try to hit the DC that lets you find a water source. If you roll below that, the DC increases by 1d4 the next day, and if you roll below that, another 1d4. After three days, your civilization falls. If you find a water source, it lasts for the number of its size in in game months, but you can also search for water sources during the time you have water. Every time you find a water source the DC increases by 1 to a maximum of 20. Any water source found on a nat 20 has a number of 100. 

There are 3 categories of water source: small, medium, and large. When you discover a water source, roll a 1d10. On a 1-5, it’s a small water source, on a 6-9 it’s a medium water source, and on a 10 it’s a large water source. Small water sources have a number of 5, medium have a number of 30, large have a number of 100. Settlements that are Village sized or larger consume an amount of water equal to their category size every month. 

You have a bonus to search for water sources equal to your category size. 

Food starts with the number you rolled on your daily food die, and it must meet your daily food requirement or else your settlement goes down a category. You can distribute food across settlements if you have enough. Citizens must not be starved for a month (day out of game) or else they will die. You can choose not to distribute food, which will save food in the long term. 

Whenever you reach a category size, you can multiply all the food you rolled (including farms) by the number in your category’s name, due to having more people to collect. 

Buildings are not a single building and instead reflect the network of buildings created of that category. One singular “Houses” building can be anything from a neighborhood to a housing complex, or however you want to flavor it.

Mine 

• Produces coal & allows for faster resource collection. When you roll your daily dice for resource collection, you may choose to add whatever the maximum roll for your metals or stone would be to the amount of metal or stone collected for that day. If you do not have a dice for metal or stone, you can choose to collect an amount of stone or metal equal to your category number. You may also convert any metal you collect to coal when you collect it. 
• Requires 5 stone and 5 lumber to build. 
• Upgrade: You can spend 10 lumber, 10 stone, and 10 coal to make the mine bigger. This allows you to roll an extra die for a resource of your choosing. If you do not have access to this resource in your biome, your die will be a d4. 

Barracks 

• Barracks let you recruit soldiers. Your first barrack level allows you to have a minor squadron, but you also have to invest the people. First upgrade (Second barrack level) allows you to have a full squadron. Third, a battalion. 
• A barrack costs 10 lumber, 10 stone, and 10 metal to create. It costs two times that to upgrade for the second level and three times the second level’s requirement to level up a second time. 

Housing 

• Requires 10 lumber and 10 stone. This houses every person in a Category 1-3 sized settlement. To upgrade, it costs an amount of stone and lumber equal to your category size multiplied by 5.
• Housing protects against the elements. Every day when you roll your daily resource collection and do not have housing but have other functioning buildings, you may choose to make one of those buildings a temporary first level housing building, which removes any other benefit that building may have given you. For every day you go without housing your entire population, roll a 1d10. On a 3 or less, your category size decreases by 1 as people die from exposure to the elements. If this reaches 0, your civilization is destroyed.

Farm

• Three variations, crop farm/animal farm/lumber farm 
• Crop farms allow you to roll an extra 1d4 food every day, this does not count towards your daily base roll. You can spend 5 food to create them and 10 food to upgrade them, which allows you to roll a d6 instead, up to a d12. 
• Animal farms allow you to add two to your food or animal products every day. If you skip a day, you can start keeping animals and collect later. If you skip a whole week, you can double the amount of animal products/food you collect at the end of that week. Or you can get mounts that will allow you to have a cavalry. Mounts populate like mortals, and when you create an animal farm, it will steadily grow larger unless you kill the animals. You can upgrade animal farms using 10 lumber, and you must upgrade animal farms whenever you reach 50 animals. The maximum upgrades you can get is ten. 
• Lumber farms work the same as crop farms, except with lumber. They require 5 lumber to create and 10 to upgrade. 

Artisan Guild

• An artisans guild is required to upgrade buildings. It costs 7 stone, 3 lumber, 5 coal, and 5 metal to build. Artisans guilds can also create armor and ships. Artisans guilds can halve the amount of one resource required for a building. 
• You can spend 1 of a resource to turn it into something. For example, you can make food twice as effective, make one metal into a suit of armor and a weapon, or turn one stone into bricks, which will make them twice as effective. 

Hunter’s Encampment

• Can also cook food, making food twice as effective (meaning citizens only require half food if it is cooked)
• With every Hunter’s encampment you have, you can add the number in your category’s name to rolls to find water, and your daily roll for food. Whenever you get a new hunter’s encampment, you can add one to that number you add to water rolls and food additions, this number can go up to ten. 
• Requires 10 lumber, or 5 lumber and 5 coal. Every day it must be given 2 lumber or 1 coal to stay burning. 

Medical Center

• Cures poisons and diseases by lowering their duration to one day, and can heal battalions' hp to maximum if they spend the night there. 
• Requires 10 lumber, 10 stone, and 5 food to build. 

Temperature Regulation

• Varies from region to region, prevents creatures native to the biome from dying to temperatures (such as in the tundra or desert)
• Allows farms to produce resources in all seasons
• Can be built using either 10 coal or 10 stone. 

Docks

• Can be built on Medium or Large water sources, roll an extra 1d4 if medium and 1d6 if large when doing food production. Removes any penalties to trading.
• Can be built using 5 lumber for medium and 15 lumber for large. 

Castle/Fortress

• Requires 50 stone, 10 lumber, and 15 metal to build. Creates a structure with an AC of 20 and a HP of 200. Anyone inside the structure cannot be harmed unless the structure drops to 0 hit points, and in that case it is destroyed. The castle counts as level 1 housing.
