Noble House Creation Tables

Inspired by the Space Marine Chapter Creation Tables, this is a Warhammer 40k noble house creator, for your TTRPG needs. Enjoy creating your own Imperial house to play as, oppose, or do whatever with! (Currently a WIP)

House Type

House Type (d100)
01-20	Imperial House - Your bog standard Imperial House that control a planet or system. Alternatively they are a Terran House.
21-40	Navigator House - This house is a navigator house. Must be taken with Age Of Strife.
41-60	Planetary House - This house is aristocracy only on their planet. Alternatively, they can be a Hive City noble. Cannot be taken with illustrious or above.
61-80	Knight House - This house is a knight house. Honestly, I'd just recommend switching to that creation table if you rolled this.
81-100	Rogue Trader House - This is a Rogue Trader house.

Relation With The Imperium

How does this House do in the Imperium? (d8)
1	Standard - Your noble house is on neutral terms with the Imperium of Man.
2	Amazing - Your noble house is greatly trusted by the Imperium, and the government knows your house will have their back.
3	Distrusted - Your noble house are distrusted, and the Imperium is always assuming the worst when it comes to this house.
4	Beloved - This house is beloved by the Imperium, and the government (local or Terran depending on your power) sing your praises when it comes to well, doing anything.
5	Loathed - Straddling the line between becoming outcast, this house is absolutely hated by the Imperium.
6	Renegade - Your House is completely disconnected and has been denounced by the Imperium. You're on your own here bucko.
7	Secret Heretics - Your house is secretly full of heretics! Roll again for what the Imperium thinks of your house!
8	Unknown - Somehow, no one in the Imperium (local or otherwise) is aware of the existence of your house.

Foundation date

When was this house founded? (d100)
1-2	Ancient Origins - A most ancient and venerable house, this noble family can trace it's origins to pre-Imperium nobility from the Dark Age of Technology or even before, going far back to the Age of Terra. Whether made up or not, the fact that their house predates the Imperium means that this family is proud of it's origins, and may hold considerable power within the Imperium. Don't mention to them that most the Imperium is probably descended from their legendary progenitor though.
3-5	Age of Strife - Similar to the above but unlike it, this house was founded during the Age of Strife, and predates the Imperium by many millennia. Whether they fought against the Imperium and brokered an agreement or worked with them the moment they were founded, this house has a most illustrious history, and may be juggernauts in the Imperial war machine or bureaucracy.
6	Unification Wars - This House was a peer of the Imperium upon it's foundation. Whether it's founder was a techno-barbarian warlord or a loyal servant of the emperor from the start, the fact is, this house eventually became one of the founding pillars in the creation of the Imperium of Man.
7-10	Great Crusade/Horus Heresy - Found upon a newly conquered world or from the many Imperial Army regiments that fought for or against the Emperor, this noble house grew up within the shadow of the Imperium. Having possibly fought within the countless battles of the Crusades and/or the Heresy, this family dates it's foundations to the days when the Emperor's light shined across the sky - or it's darkest moments when traitor legions tore the Imperium asunder.
11-20	Time of Rebirth - This house's progenitor was born during the time of rebirth, perhaps during the Scouring or after The War of The Beast.
21-30	The Forging - This house's progenitor was active during The Forging, perhaps after the terror of The Beheading or during one of the crusades taken during this period.
31-50	Nova Terra Interregnum - This house's progenitor lived during the Nova Terra Interregnum, and may either have supported the Imperium, or supported Nova Terra and walked back to the Imperium's fold.
51-70	Age of Apostacy/Redemption - Maybe it was founded with the help of Goge Vandire himself, maybe they helped overthrow him - or maybe both, the progenitor of this house was founded upon the Age of Apostacy or The Age of Redemption.
71-80	Age of Waning/Time of Ending - A rather recent noble house that has found itself rising through the ranks of the Imperium of Man, this is one of the newer houses within the Imperium. It may only consist of a nuclear family or already be a few centuries old, but whether this family will retain it's grasp on power is yet to be seen.
81-100	Age of the Dark Imperium - This is a brand new house, barely consisting of more than a few members. Their members are still fresh and idealistic, or perhaps the most corrupt and rotten. May not be taken with decadent.

House Temperament

What is this house like? (d100)
1-2	Noble - A house of idealistic individuals, this noble house is genuinely noble and believe that they are working for the greater good. Whether they are mislead or genuinely kind, these people are exemplars of nobility, an island of integrity in a sea of corruption. Think House Atreides and you're on the right track.
3-5	Decadent - A house full of lazy and cruel individuals who see everyone else as beneath them. Think of pretty much every depiction of aristocracy in current 40k works (or heck, popular perception) and you'd get the general idea. Probably heretics too.
6	Cutthroat - A house of sociopathic cutthroats, this house seeks to gain - or retain power at all costs.
31-50	Insulated - This house is so disconnected from reality, they don't even register the troubles of the rest of the Imperium as anything more than a distant concern.
51-70	Ambitious - This house is full of drive, and wants MORE power, whether that be for malicious reasons, genuinely altruistic reasons, amoral powerhungryness, or a cocktail of any of them.
71-80	Unassuming - Not every Noble House has to be full of great or terrible individuals. This house is full of normal, if not slightly spoilt people.
81-100	Complex - Roll for two Temperaments. Noble cannot be taken with decadent or cutthroat, and insulated/unassuming cannot be taken with cutthroat or ambitious. Otherwise, go wild! Reroll on any incompatible temperaments or duplicates.

Power Base

How Does this House Retain Power? (d100)
01-20	Planetary Fiefdom - Your noble house owns a planet, and collect taxes from the citizenry.
21-40	Resource Extraction - Your noble house extracts resources, whether that be from a planet they own or from mining asteroids and the like.
41-60	Market and Commerce - Your noble house are merchants, working in commercial or industrial businesses.
61-80	Ecclesiarchy Priesthood - This house is a Ministorum ally, and has a family legacy of rites, rituals, and practices. In turn, they are held up by the Ministorum.
81-100	Several Specialties - Roll twice more on the table!

House Strength

How much fame and power does this house have (d100)
01-20	Micro - This is a tiny house, at least owning a city sized fiefdom. Anything below that is barely worth mention.
21-40	Continental - This house has at least a continent's worth of resources, or a hive city's worth.
41-60	Minor - This house has the resources to be top dog in their own planet, a barely known backwater. Alternatively, they are a continental sized house on an incredibly famous planet.
41-60	Notable - This house has the resources to be top dog in their own planet, a planet widely known throughout the Imperium. They can also be powerful and famous in an obscure subsector. This is the minimum tier to be noticed by the galaxy at large, thought that is debatable in on it's own.
61-80	Major - This house is renown house, having multiple subsectors knowing their name. They are known throughout the sector as a great house of great power.
61-80	Great - This house is known and hold some influence throughout the segmentum.
61-80	Illustrious - This house is known and hold considerable influence throughout the segmentum.
61-80	Titanic - This house is known and hold influence throughout the Imperium.
61-80	Venerable - This house is directly connected to the High Lords of Terra and can thus wield considerable influence in the Imperium.
81-100	Fallen House - This family has fallen from grace and now sits at a lower tier than they once did. Roll to see what they were before or at their peak, and where they are now. Alternatively, you can make them impoverished nobles, barely doing any better than the common folk. This means that a lot of what you rolled for is in the past tense.

Resources

Ties With (d10 roll 3 times)
1	Space Marine Chapter - This noble house has connections with a chapter of the Adeptus Astartes. They may send some of their sons over as applicants or as chapter serfs, or just have worked with them many times in the past, but regardless, they are a house well acquainted with this chapter.
2	Administratum - This house may be an Administratum dynasty or have many members working in high positions in the Administratum. Either way, this house has the immense resources of the Administratum to work with.
3	Imperial Military - This house may have a long and illustrious history of service within the Imperial Guard or Navy, or simply have the right friends. Either way, this house has connections to the Astra Militarum.
4	Ecclesiarchy - This house is on good terms with the Imperial Church. This is obviously a good thing.
5	Criminal Organisation - Anything from a xeno-trading cartel to narcotics barons, this noble house retains shady connections for profiteering uses - or for doing their dirty work. Cannot be taken with a noble temperment.
6	Inquisitor - Whether the inquisitor in question is a member himself or is merely close friends, this house has connections to an Inquisitor, giving them a powerful advantage over others.
7	Imperial Government - The House has friends in high places within a particular region's government, be it a Sub-Sector, Sector or even a Segmentum. Alternatively, they are the government.
8	Their Subjects - This house is actually respected by their subjects, who trust them and work with them. Cannot be taken with decadent.
9	Heretical cult - This family is associated with a heretical cult, whether knowingly or not. Alternatively, this can be a genestealer cult, and are unaware that this is a ticking time bomb that will ultimately ruin their family either way. Can automatically be taken with traitor.
10	Xenos - Maybe they are close friends with an Eldar craftworld, an Exodite World, a Tau world, or some other xenos race. Depending on if they are sanctioned xenos or not, this may be a secret. Can automatically be taken with traitor.

Armed Forces

House Army Type (d100)
1-30	Mercenaries - The House primarily uses mercenaries to guard themselves. Better pay them well!
31-60	House Troops - A body of professional soldiers, loyal to the House. How well armed they are depends on the status of the house.
60-90	Imperial Guard - This family is protected by the Imperial Guard.
91	Exotic - Anything that is not covered here. Alien mercenaries (Kroot or Orks?), renegades, mutants, abhumans, Adeptus Astartes, alien sponsors/allies (Tau or Eldar?), Chaos forces (Traitor Legions, most suited to the Alpha Legion, or deceived fools)
92-100	Mixed Forces - roll twice on the table!
