Nibiru - Basic Math


For a full-res map

I have previously posted a map for my Nibiru sword & planet setting for ACKS. Now, it is time to do some basic mathematical calculations about this setting, using the ACKS rules.

Nibiru is a dying planet and population is low. In "civilized", cultivated areas such as the city-states, population density is 40 people per square mile, that is, 250 families per 6-mile hex. In desert areas, even with mining and some cultivation, population density is 20 families per square mile, that is, 125 families per 6-mile hex.

Built around city-states with some remnant Ancient technology, Nibiru is an "Advanced, Urban Realm" (2 rows downward on the ACKS p.231 urban population table) and has a very "Centralized Settlement Pattern" (2 rows downward for the Largest settlement).

The city-state of Anurash controls 53x "civilized" 6-mile hexes, and thus has an approximate population of 13250 families, placing it somewhere between a county and a duchy in ACKS terms. Thus, Anurash is a City (Class III market) of approx. 3000 families, out of approx. 4000 urban families in the realm.

The city-state of Ennung controls 42x "civilized" 6-mile hexes, and thus an approximate population of 10500 families, placing it somewhere between a county and a duchy in ACKS terms. Thus, Ennung is a Small City (Class IV market) of approx. 1500 families, out of approx. 2500 urban families in the realm.

The city-state of Erida controls 63x "civilized" 6-mile hexes and thus an approximate population of 15750 families, placing it somewhere between a county and a duchy in ACKS terms. Thus, Erida is a City (Class III market) of approx. 3500 families, out of approx. 5000 urban families in the realm.

Desh is a fortress-village controlled by Erida. It has a population of 200 families, making it a Village (Class VI market).

Kur is a fortress-village controlled by Erida. It has a population of 250 families, making it a Village (Class VI market).

The city-state of Edin controls 48x "civilized" 6-mile hexes and thus an approximate population of 12000 families, placing it somewhere between a county and a duchy in ACKS terms. Thus, Edin is a Small City (Class IV market) of approx. 2000 families, out of approx. 3000 urban families in the realm.

Telal is a fortress-village controlled by Edin. It has a population of 150 families, making it a Village (Class VI market).

Zag, an independent fortress, controls 7 desert hexes. Thus, 875 families in total, making it almost a March (or a huge barony) in ACKS terms. Thus, Zag is a Village (Class VI market) of approx. 100 families out of approx. 500 urban families in the realm (most locals live from commerce and a little subsistence farming rather than more extensive agriculture).

Barzal, an independent fortress, controls 12 desert hexes. Thus, 1500 families in total, making it a huge March in ACKS terms. Thus, Barzal is a Village in ACKS terms, and would be a Class VI market by RAW, but I'd making it a Class V market due to extensive mining and trade. Barzal has 200 resident families, out of the realm's total of 400 urban families. Most economic activity here is mining and commerce, and much of the food comes from traders.

Helix is a village controlled by Barzal. It has a population of 75 families, making it a Small Village (Class VI market).

Meshanna, an independent fortress, controls 5 desert hexes, and thus has a population of 625 families, making it almost a March (or a huge barony) in ACKS terms. Thus, Meshanna is a Village (Class VI market) of approx. 100 families out of approx. 150 urban families in the realm (most locals live from commerce and mining and a little subsistence farming rather than more extensive agriculture).
