The worlds of the galaxy, and most notably of the Imperium, can be categorised into several broad classifications. The following list is for cursory details only, and a greater depth of detail can be found by reference to the relevant hyperlinks and each classification below contains examples of such designated planets which can be used for a strategic analysis of specific political, economic and cultural phenomena and trends of that category which can be extrapolated to cover most instances of that planetary type. These worlds are listed for flavour, feel free to add more information or background or make them the centre of your campaign. Gameplay Note: These descriptions are the higher level generalised classifications than the UWP in T20. You can add the prefix of the Warhammer 40k world type in front of the T20 UWP, for example, C432430-8 becomes h-C432430-8 signifying a Hive world. Or you can include the w40k descriptor (e.g. Forge World) in the Trade Classification section. Or not use it at all. I have included a UPP decrypter courtesy of the Explorator branch of the Ministronum.

Urban conglomerations called Hives, many miles in height, are principle population centres. Factory, mining and atmosphere processing are main industries. High import/export ratio, particularly foodstuffs and fresh water incoming. Cross-reference: Armageddon, Avellorn, Ichar IV, Kado, Lastrati, Mordia, Necromunda, Vanaheim. |
| g-class [Civilised Worlds] |
Population: £10,000,000,000 ³15,000,000 Tithe Grade: Solutio Extremis-Exactis Tertius Aggregate: 3,500: Aestimare: A50-F1000 Comments: This is the widest category comprising any world, generally self-sufficient, with a contemporary technology base that does not comply with other specification. Includes major sub-categories Cardinal Worlds [cc], Garden Worlds [cg], Mining Worlds [cm]. Cross-reference: Desedna, Espandor, Korsk II, Rhanda, Tallarn, Valhalla, Zerona. |
| Population: £1,000,000 ³15,000 Tithe Grade: Exactis Prima-Exactis Particular Aggregate: 2000: Aestimare: C500-B50 Comments: No less than 850 parts per 1,000 given over to the cultivation of crop, hydroponics, animal fodder or animal husbandry. Few conurbations, population spread widely across planet surface. Cross-reference: Bellius XIV, Chiros, Kabaal II, Silvanos II, Verdan III. |
| Population: £5,000,000 ³100,000 Tithe Grade: Solutio Tertius Aggregate: 800: Aestimare: F400-G800 Comments: Technical base considerably pre-black powder, even pre-ferrous or lithic state in most regressed cases. Sometimes good source of army and Adeptus Astartes recruits if culture shock survived. Low tithe due to unfocussed production processes. Imperial Commanders often distant, in orbit usually, with infrequent surface forays to establish purges of psychic talent and mutation. Cross-reference: Belami, Davin, Fenris, Forman C2, Kimmeria, Oran. |
| Population: £1 [exc. Imperial facilities] Tithe Grade: Aptus Non Aggregate: 200: Aestimare: G500-G1000 Comments: These worlds have minimal, even non-existant, life traces. This results from ecological catastrophe, devastating internecine war, Imperial or alien intervention or no attributable cause. Cross-reference: Isvaan III, Naogeddon, Prandium, Truan IX, Zhoros. |
| Population: £15,000,000 ³1,000 Tithe Grade: Solutio Tertius-Solutio Prima Aggregate: 600: Aestimare: D500-G50 Comments: Planets which are too dangerous to support widespread human settlement. Types may vary from world-wide jungles that harbor carnivorous plants and animals to barren rockscapes strewn with volcanoes and wracked by ion storms. These worlds are near-impossible to colonise but must be properly explored which necessitates the provision of outposts and other facilities. Some harbour rich mineral, vegetable, animal or gaseous resources. Cross-reference: Canak, Catachan, Lost Hope, Miral, Piscina V. |
| r-class [Research Stations] |
Population: £500,000 ³100 Tithe Grade: Adeptus Non Aggregate: 100: Aestimare: A760-D45 Comments: Includes wide variety of locations, such as orbital stations, asteroidal emplacements and other major facilities of dead worlds, death worlds or on other planets. Responsible for wide variety of research, from animal breeding and domestication to weapons testing and gene engineering. Also listening and watch posts for planetary and system defence of major planets [Aest. B200 or greater]. Cross-reference: A1709, Arx, Fornoth, Lucan, Purgatory, Sentinel V, Ymgarl. |
| Population: £500,000,000 ³10,000,000 Tithe Grade: Solutio Prima-Solutio Extremis Aggregate: 400: Aestimare: C750-F1000 Comments: Technical base just prior or just post-black powder state. Establishment of wide surface cultural and political organisations. Some useful recruiting for Imperial Guard and Adeptus Astartes. Slightly higher than feral worlds, compensating for wider farming and animal husbandry. Cross-reference: Attila, Boras Minor, Chbal, Molov, Solstice, Yamnan. |

A forge world often serves as a base of operations for one of the Titan Legions. Forge worlds are essential for the supply of arms and armour to the Imperium's combat forces.
