Non-code, non-skilled, non-anything anon attempting to contribute.
Highest population, high tech, high production and/or manufacturing, good recruiting (possibly good penal legionaire production) High AdMech influence.
Needed to support hive and Forge worlds. Possibly others, to varying degrees. Some ought to produce luxury foods, for nobles and shit-maybe more valuable?
Highest Manufacturing. Decent-to-high population. AdMech ownage.
Production of raw materials
People-producing, wealth-producing, as they likely have high demand for high-tech goods and unique natural resources. Less tech, better recruits/tougher inhabitants. Good production/manufacturing, but limited tech.
Tougher recruits, more natural resources, though less likely to industrially exploit it. Low tech, obviously. Low, but possible AdMech presence.
Lowest tech, tough recruits, I'd assume. Potential AdMech presence, but most unliklely. (Either requiring local AdMech relics, or some other bizarre reason for them to take interest.)
Ignorant of what this would really entail, aside from Ecclisiarchal strongpoint and morale-penalty if lost. Maybe bonuses from pilgrims?
Again, I literally don't know what this would be. Guess: Perhaps some bonus to nearby agri-worlds? Converts human bodies back into fertilizer? No clue.
Nobles, Inquisitors, etc. High morale, wealthy, low production, manufacturing, etc.
Obviously, there should be a variety of these. Ones off the top of my head that I've heard about: Pandemic, haunted (Mara Landing Massacre, Dark Heresy), warpstorm'd (DoWII, Chaos Rising), unconquerable (Ganymede, some Solar Macharius fluff), and probably more that I simply don't know.
