Overview
Gnomes are diminutive humanoids defined by an infectious curiosity that does not diminish with age. They stand no more than 4 feet tall as a rule, their compact frames a contrast to the wealth of information, scheme, and enthusiasm packed inside them. Their eyes β twinkling, sharp, perpetually interested β range from mossy green to cobalt blue, and their faces carry an almost constant hint of mirth, as though the world is presenting them with a puzzle they expect to solve shortly. Their hair defies expectation in color and chaos: reds, greens, blues, earthy browns, sometimes two shades at once. Most gnomes look, to outside observers, like they were assembled in a hurry by someone who had strong feelings about the result but limited interest in conventional aesthetics.
They come in two primary lineages. Forest Gnomes live close to natural systems and have developed an affinity for the living world β the language of small animals, the subtle currents of the Feywild that bleed into old growth, the way weather changes three days before the change is visible. Rock Gnomes channel their curiosity into mechanical and arcane craft, building with an inventiveness that consistently produces results that shouldn't work but do. Both share the underlying gnomish quality: a delight in complexity, a willingness to try the thing that probably won't work, and an unwillingness to be boring.
What gnomish communities are most often noted for β by peoples who spend time among them β is a quality of engaged aliveness that is difficult to describe without sounding excessive. Being in a gnomish settlement feels like walking into a place where everyone is in the middle of doing something they genuinely care about. Conversations overlap. Projects are spread across every available surface. Someone is always just discovering something, and the discovery is always worth interrupting everything else for. The effect on visitors varies: some find it exhilarating, some find it exhausting, and some find it both in rapid alternation.
Within the Yggdrasil setting, gnomes are found wherever there is something interesting to investigate. Academic institutions contain them in disproportionate numbers. Artificer workshops are often gnome-founded or gnome-led. Diplomatic courts prize gnomish advisors for their ability to model complicated scenarios and identify non-obvious solutions. And adventuring parties frequently find that the gnome they picked up for one specific job turns out to be useful in seven ways they didn't anticipate, because gnomish preparation tends toward the thorough.
Culture
Gnomes have no unified homeland in the Yggdrasil setting. Their communities are small and scattered, often embedded in the cities and institutions of other nations. What follows describes patterns common across both lineages.
The Two Traditions
Forest Gnomes and Rock Gnomes share a common ancestry and a common restlessness, but their traditions have diverged meaningfully. Forest Gnomes organize their curiosity around living systems β ecology, weather, the behavior of animals, the slow grammar of forests. Their communities sit in or near old growth, and their scholarship tends toward the holistic: they want to understand how things relate to each other rather than how they work in isolation. Forest Gnome knowledge is deep on interconnection and sometimes thin on mechanism, which Rock Gnomes consider a character flaw.
Rock Gnomes reverse this. Their curiosity is directed at mechanism β how the thing works, what makes it go, what happens when you change one variable. Rock Gnome workshops are organized chaos: layered projects, experimental failures stacked with systematic notes about why they failed, and a general understanding that progress is a staircase made of broken things. Their knowledge is deep on mechanism and sometimes thin on context, which Forest Gnomes consider a character flaw.
The two traditions have enough mutual respect to work together effectively and enough genuine disagreement to keep things interesting. Mixed communities β which are common, since gnomes follow interesting problems wherever they lead β tend to produce the best work either tradition has to offer, because each keeps the other honest about its blind spots.
The Relentless Question
Gnomish culture treats curiosity not as a personality trait but as a civic virtue. A gnome who stops asking questions is viewed with the same concern another culture might reserve for someone who stopped eating. Communities organize themselves around what they are collectively interested in β a gnomish settlement near a natural hot spring might spend three generations studying it, mapping it, theorizing about it, arguing about the theories, and eventually producing a definitive work that raises seventeen new questions. This is considered a success.
The way gnomish communities teach young gnomes is almost entirely through questions rather than answers. An elder who responds to a child's question with another question is not being evasive β they are doing their job. The goal is not to transmit information but to model the practice of investigation: asking the right question is harder and more valuable than knowing the answer, because the right question points you somewhere new. Gnomes who were raised in non-gnomish communities often describe, as adults, a vague sense that they were supposed to be learning something different from everything they were taught.
This question-first orientation applies to moral reasoning as much as empirical investigation. Gnomish communities are rarely dogmatic; they tend toward ethical frameworks that treat principles as hypotheses to be tested against specific situations rather than rules to be followed regardless of outcome. This makes them flexible and sometimes makes them seem evasive to peoples who want a straight answer.
Memory as Craft
Gnomes do not have elven centuries of lifespan, but they compensate by being exceptionally deliberate about knowledge transmission. Oral traditions, meticulous records, and the practice of formal apprenticeship ensure that what a gnomish community has figured out does not leave when its experts do. Rock Gnome workshops in particular maintain detailed logbooks spanning decades β not for posterity, but because you never know when you will need to understand why the second iteration of the project failed.
The logbook culture extends beyond workshops. Gnomish families maintain household records that cover not just practical information but observations, theories, and running arguments β debates started by grandparents that their grandchildren are still prosecuting with new evidence. These records are consulted regularly and updated actively. A gnomish household that has been in one place for several generations has, in its records, a detailed account of everything that has happened in that neighborhood for as long as anyone can remember. Local governments have learned to treat gnomish household archivists as an underutilized civic resource.
Gnomish scholarship prizes the negative result β the experiment that confirmed what does not work β as highly as the positive discovery. What does not work is information. Knowing what does not work tells you something about the shape of the territory. A gnomish researcher who publishes a careful account of a failed approach is doing the community a service, and the community understands this. This norm is not universal across the setting's academic institutions, and gnomish scholars in mixed-species institutions often find themselves in frustrating disagreements about what counts as publishable work.
Gnomes & Institutions
Gnomes thrive in institutions that reward curiosity and tolerate disorder, and struggle in ones that don't. They are overrepresented in universities, research councils, artificer guilds, and the more analytically oriented branches of diplomatic service. They are underrepresented in military command structures, strict religious hierarchies, and anywhere that values conformity of process over quality of outcome.
Within the nations of the Yggdrasil setting, gnomish communities cluster in cities with strong academic or commercial traditions. They rarely hold political power directly β both because gnomish communities tend to be small and because gnomish individuals are often more interested in the interesting problem than in the position. But they are present as advisors, specialists, and the people who quietly figured out the solution to the thing that was bothering everyone else.
The relationship between gnomes and the larger institutions they serve is generally positive but periodically strained by the gnomish tendency to pursue interesting problems past the point where the institution wanted them stopped. A gnomish researcher who discovers that the answer to the question they were hired to investigate points toward a question the institution does not want answered is in a position that most gnomes find morally clear and most institutions find infuriating.
Small People, Strong Nerves
Most gnomes have had to develop a functional relationship with a world scaled for larger beings. They are not naΓ―ve about this. The resilience gnomish culture prizes is partly physical β the Gnomish Cunning that lets them resist magical compulsion β and partly the resilience of people who have learned not to be intimidated by things that are simply bigger than them.
This produces a particular kind of social confidence that can be mistaken for obliviousness. A gnome who strides into a room full of Goliaths and proceeds to take over the conversation has not failed to notice the size differential. They have assessed it, determined it is irrelevant to the matter at hand, and moved on. The gnomish community considers this the correct response. Large peoples who interact regularly with gnomes tend to agree, after enough exposure, that the gnome's assessment was probably right.
The practical effect is that gnomish communities have a remarkable track record of punching far above their weight in institutional contexts β not through force but through the kind of thorough, persistent engagement with the actual problem that larger peoples often cannot sustain at gnomish intensity. You do not out-prepare a gnome. You can sometimes out-wait one, but they will make the wait interesting.

Forest Gnome β You know the Minor Illusion cantrip. Wisdom, Intelligence, or Charisma is your spellcasting ability for it (chosen when you select this lineage). You can also cast Speak with Animals as a Ritual. Once you cast either spell with this trait, you can't cast that same spell with it again until you finish a Long Rest. You can also cast either spell using any spell slots you have. Rock Gnome β You have proficiency with Tinker's Tools. Using those tools, you can spend 1 hour and 25 GP worth of materials to construct a Tiny clockwork device (AC 5, 1 HP) that lasts until you use this trait to make another or until you die. You can have up to three such devices active at a time. When you create a device, choose one of the following options: Clockwork Toy, Fire Starter, or Music Box. (See the 2024 PHB for full descriptions of each.) Once active, the device functions for 24 hours unless its mechanism is destroyed."
Designer Note
Gnomes are built around intelligence and resilience β Gnomish Cunning's broad saving throw advantage is deceptively strong and rewards players who engage with the setting's magical hazards. The two-lineage structure creates meaningfully different character concepts within the same species. Encourage players to think about what their gnome is currently obsessed with investigating β gnomish characters without an active intellectual project feel slightly off-brand.
