I very much like the “circuits” idea as well. Very High Middle Ages in Space, with distance forcing decentralization requiring Rube Goldberg governance structures, which is dead-on to the theme of the setting.
Now, running statistics:
Chris says
Number of Systems per District: 1d10
Value: 1d10-2
For a Value 3 or higher independent system, roll 1d6-1 to determine its index (ie 0-5 index).
For a Value 2 or lower independent system, roll 1d6-3 (ie 0-3 index).Sector Capital: Index + Val = 10+
Industrial World: Index + Val = 9-10
Resource World: Index + Val ≤ 8
Since Resource Worlds can’t support a Forged Lord, we don’t have to worry about the second formula for Tech Index: It’s mathmatically impossible for a system with Value of 2 or less to get a high enough Tech Index for the total to exceed 8 and make it an Industrial World.
So, we have, assuming Sector 311’s density of worlds is average, and that its “Independent” systems are representative of the Tech Index of the rest of the Iron Empires (unlike its Karsan systems, which are explicitly stated in the Brick to be atypically high in their Indices):
Sector Capitals 10%
Industrial Worlds 15%
Resource Worlds 75%
Average District - rounded values (true values):
Sector Capitals 1 (0.55)
Industrial Worlds 1 (0.825)
Resource Worlds 4 (4.125)
Total Worlds 6 (5.5)
Now, there are 25 Districts per Quadrant, and four Quadrants, totalling 100 Districts, per Sector (see Chris’s notes on astrocartography, or just eyeball the Sector 243 map). That produces
Average Sector:
Sector Capitals 55
Industrial Worlds 83 (82.5)
Resource Worlds 413 (412.5)
Total Worlds 550
Now, it’s not stated anywhere I can find how many Sectors there are in the Iron Empires, and the PDF version of the IE map from pg. 28 of the Brick which I have at work is too blurry for me to make out the key (dammit), but the Astrography page states the entire Hanrilke realm is roughly 2,000 light-years on a side, and a Sector is 200 ly on a side. That suggests that the space occupied by the successsor states is 10 Sectors by 10 – although this doesn’t jibe with the gridlines on the map (sigh).
Anyway, assuming the Iron Empires occupy an area of 100 Sectors – Chris, please correct me if I’m wrong! – then
[EDIT: deleted incorrect calculations to avoid confusing posterity]
Now, as I’ve said, my assumptions may be significantly off.
