Subterranean environments are those lying wholly beneath the surface of the earth, where the ordinary order of the world gives way to darkness, confinement, damp stone and the perpetual uncertainty of what lies just beyond the edge of a lantern's glow. These places are not merely "underground" in the physical sense, but are distinguished by a change in conditions that affects movement, visibility, morale, habitation and danger. A party entering a subterranean place does not simply go indoors; it enters a world where direction is uncertain, escape is often difficult and the ground itself seems to conspire against confidence.

The smallest form of subterranean environment is the simple den or burrow: a cavity clawed or dug into the earth by animals, monstrous beasts or solitary intelligent creatures. Such places may consist of only a winding tunnel, a nesting chamber and perhaps one or two side hollows for refuse, food or sleeping. These are often entered and understood in a matter of minutes, but this simplicity does not make them safe. A burrow's narrowness can prevent easy fighting, force adventurers to crawl or stoop, and place them at the mercy of creatures that know every turn and choke point. A single occupant encountered in such a place may be more dangerous than a score of enemies met in the open, because the environment belongs wholly to it.

More formidable are the excavated warrens and labyrinths found beneath lonely hills, in escarpments, below ruined towers or under stretches of forest and scrub where no traveller would suspect habitation. These are often the work of goblins, kobolds, orcs, brigands and other raiding peoples who have learned that what cannot easily be seen cannot easily be besieged. A hidden entrance, a trapped shaft, a crawlspace beneath roots or a disguised cleft in stone may open into a defended underworld from which sudden attacks can be launched against roads, hamlets, caravans and isolated farmsteads. Such lairs serve not only as shelter but as military works, storing loot, captives, arms and provisions. In campaign terms, these are often the first true subterranean strongholds a party encounters: not yet grand, but organised enough to imply discipline, patrol routes, guard stations and a degree of permanence.

Where occupation below ground has endured for generations, these refuges may develop into complete underground settlements. Certain peoples are not merely tolerant of subterranean life but adapted to it, whether by custom, physique, temperament or necessity. In such places one may find carved chambers serving as homes, shrines, granaries, workshops and meeting halls, all connected by passages widened and maintained over decades or centuries. The life of these settlements is not a mere imitation of surface existence, but a distinct mode of living. Water is drawn from underground streams or cisterns, refuse is carefully managed, and whatever may be raised in darkness or dimness becomes precious. Pale fungi, root crops, cave fish, blind vermin, beetles, bats and other hardy or unnatural stock may form the basis of food production, while pens and chambers may be set aside for creatures bred entirely to underground conditions. Such places need not be civilised in any sentimental sense, but they are inhabited, purposeful and self-sustaining.

Beyond these are the great deep places: the true dungeons, the ancient cave systems, the buried temples, collapsed cities and descending vaults that extend far beyond the practical understanding of those above them. These are not simply shelters but domains. They may have been shaped by forgotten empires, cults older than the memory of the local people, vanished races, exiled magicians or powers whose works were never intended for sunlight. Such places are often multi-layered, with upper levels altered by later inhabitants while deeper portions remain untouched, sealed, flooded, cursed or occupied by beings for whom the surface world is an irrelevance. In these environments, the subterranean becomes not just a setting but a descent into increasing strangeness. Architecture changes. Air quality changes. Sounds travel in uncanny ways. The very scale of halls, shafts and caverns begins to imply purposes no human mason would have had.

It is in these deeper reaches that may hold the chambers of an ancient cult, still stained by ritual and fear, where passages lead not according to utility but according to religious symbolism or derangement. A subterranean place may conceal the planning halls of a malevolent species preparing incursions against the upper world, their schemes carried on in black galleries where maps, idols, armouries and breeding pits coexist. It may contain old prisons whose locks no longer correspond to any key known above, treasure vaults protected by architecture itself or shrines raised to powers never worshipped in the daylight lands. Such places possess a density of intention. Every chamber suggests either a former purpose or the loss of one.

A particularly useful form of subterranean environment in campaign design is the hidden understructure beneath an otherwise ordinary or imposing surface site. Beneath a keep, abbey, palace, manor, tower or fortress there may exist an entire lower world unknown in its full extent even to the current owners. A wine cellar leads to a blocked arch. A cistern chamber opens into an older crypt. A stair behind a wall descends to rooms whose doors bear no relation to the building overhead. These spaces may have been added by successive generations, forgotten in civil war, sealed after scandal or simply lost because no one living has had reason to map them. In this way, the subterranean can exist not as a separate location but as the secret underside of civilisation itself. This has excellent AD&D colour because it allows the ordinary and the uncanny to touch directly: a lord may dine above while something impossible waits below, separated only by a few feet of stone and the accident of ignorance.

Conditions

Characters moving through a subterranean environment are conscious first of what the place does to their bodies. Light is never assumed. Even when illumination is available, it is finite, unreliable and always at risk of being extinguished, dropped or consumed. A character who has light feels its value constantly, while one who has lost it is immediately aware of helplessness, hesitation and exposure. The dark below ground is not the same as night on the surface; it is total, enclosing and without horizon, making even a familiar passage feel uncertain after only a few steps.

Fatigue accumulates differently below ground because the body is rarely permitted to relax fully. Rest is possible, but seldom easy. The stone is hard, the air often damp, and the sense of danger close enough that sleep is shallow unless precautions are taken. Blankets, wraps and dry coverings become more important than they might seem above ground, not merely for comfort but to preserve strength. Characters attempting to rest in such places are likely to wake stiff, chilled and poorly recovered unless they have secured some measure of warmth and dryness. This is especially true when the company must sleep in armour, keep watches close together or remain alert for sounds in the dark.

Moisture is one of the most oppressive features of the subterranean world because it lingers. Clothing that becomes wet through seepage, stream crossings, dripping walls, sweat or exertion does not readily dry in enclosed underground air. A character may begin the day merely uncomfortable and end it shivering, heavy-limbed and slow, all because garments have remained damp against the skin for hours. In such conditions, hypothermia is not the result of winter weather alone but of exhaustion, wetness and the body's gradual loss of heat. A soaked adventurer underground may become impaired without realising how quickly condition is declining, especially after climbing, fighting, hauling gear or labouring under load.

The ordinary temperature of most subterranean places tends towards brisk or cool, not necessarily freezing, but cold in a way that settles into muscle and bone over time. This kind of cold is insidious because it does not always announce itself dramatically. It numbs fingers, shortens patience, encourages silence and makes every pause feel longer than it is. Characters at first may welcome the relief from surface heat, only to discover later that the body has been losing resilience hour by hour. Once tiredness, dampness and darkness combine, the environment begins to sap confidence as much as strength.

The deeper such a place extends, the more oppressive these conditions become, not because every lower level is automatically colder or wetter, but because retreat becomes less immediate and ordinary relief less available. A party operating far below the surface feels the growing burden of distance: the knowledge that warmth, dry bedding, cooked food and true safety are not close at hand. Hunger is felt more sharply when meals are cold or hurried. Sleep becomes more valuable because it is harder to obtain. The body begins to measure every decision in terms of endurance. Characters who push too far without thought to recovery may find that their greatest enemy is not a monster or trap but the steady wearing down of morale, heat and strength. In prolonged descent, survival depends less on boldness than on preserving the body's ability to continue.

-'''Subterranean''' environments include underground lairs, cave labyrinths and [[Dungeon|dungeons]], where the setting is below the land's surface in a dark and dangerous place.  Some of these places are merely a burrow carved into the earth, which can be explored in a few game minutes and the creatures within met almost at once.  Another form is a humanoid garrison that has been built below the surface to allow raids upon the local area through providing a refuge that is difficult to find.  These can develop into underground villages for races that are comfortable dwelling below ground, where crops and animals bred to the subterranean environment can be raised to provide food.

-Still other subterranean places are sprawling, multi-layered palaces, protecting ancient cult, humanoids that dwell very deep in the ground or where fiercely malevolent creatures make plans to wreak destruction upon the surface world.  Another form consists of secret rooms and chambers beneath vast citadels and fortresses, where even the owners of such places remain certain of what spaces exist "down there," built by some mad ancestor generations ago.

-Characters moving through this environment must take precautions with regards to [[Illumination|illumination]] and the use of blankets in order to [[Rest (healing)|rest]] properly.  Wet clothes won't dry properly, so that [[Hypothermia|hypothermia]] is a threat if characters get soaked or work too hard.  Temperatures are typically [[Brisk Temperature|brisk]] to [[Cool Temperature|cool]].  Really deep dungeons will require preparations for rest and sleep in dangerous conditions, and depots may need to be set up to permit returns to safe places where food can be gotten.
