- Academics: Grants the ability to write Low Gothic along with some knowledge of arts, economics, books, and local planetary culture. Generally reserved for more connected or well-to-do members of the Imperium.
- Adeptus Terra: Knowledge not only of the Adeptus Terra itself, but of the many Adepta that make up the structure of the Imperium. This specialisation does not necessarily confer knowledge of any but the most well known members of any particular organisation, but it does cover knowledge of the roles and responsibilities of these organisations and their position with the Imperium at large.
- Planet: Specific knowledge about a particular planet, which must be chosen when this specialisation is first taken. For example, Lore (Juno) knowledge about the world of Juno, its customs, governance, locations, hazards, and so on. It is possible to take this specialisation more than once. Each time you do so, choose another planet.
- Sector: Broad knowledge about a particular Sector, which must be chosen when this specialisation is first taken. For example, Lore (Askellon Sector) would cover the subsectors, power structures, important figures, and general place of the Askellon Sector within the wider Imperium. It is possible to take this specialisation more than once. Each time you do so, choose another sector.
- Theology (Restricted): Training in the Imperial Creed, including various sects and interpretations. Passing knowledge of the Cult Mechanicus. Only cursory knowledge at best of any heretical sects of the Imperial Creed and none whatsoever of any forbidden cults. Theology requires at least 1 Advance in Linguistics (High Gothic).
- Forbidden (Various, Restricted): Knowledge and training in a specific subject that is utterly suppressed within the Imperium. Knowing information about aliens or psykers without specific dispensation from a powerful individual or group can get you in serious trouble. True knowledge of Daemons can get you summarily executed. Any knowledge of the immaterium, beyond common myth, is typically strictly obscured within the Imperium, as is real knowledge about the Adeptus Astartes. Each Forbidden Lore requires taking a corresponding Forbidden Knowledge Talent in order to learn it.
Lore measures how much a character knows about a particular topic. While some of this knowledge can come from perception and practical experience, much of it must come from careful study. Ignorance is sometimes an effective defence against the Darkness, but understanding can also help one learn how to overcome it.
