Footsteps Beneath | Underdeep Survival Book
A hard-bitten Underdeep survival book for those who must walk the lightless roads below the world.

Overview
Footsteps Beneath is a thick, battered field tome written for travellers who expect the underworld to kill them. It is not a courtly romance, a philosophical work, or a scholar’s comfortable account of distant caverns. It is a practical manual of spoor, tunnel air, edible fungus, poisoned water, drow patrol signs, slave-road markings, cave-in warnings, panic control, and the discipline of staying alive beneath miles of stone.
The book’s true author is uncertain. Most copies attribute it only to an unnamed elven survivor, warrior-scholar, or underworld scout who lived long enough among the deep roads to understand them better than most surface-born travellers ever could. Some traditions claim the author was a lone veteran of a destroyed elven settlement. Others insist the book is a collected manual assembled from generations of scouts, escaped captives, and drow-hunters.
What matters is that the lessons work.
Footsteps Beneath does not teach heroism. It teaches where not to sleep, which dripping sounds mean clean water and which mean something is feeding nearby, how drow scouts mark a taken road, when silence is natural, and when silence means an ambush has already begun.
For surface-born adventurers, Footsteps Beneath can be the difference between an expedition and a disappearance.
Physical Description
Footsteps Beneath is a heavy folio bound in dark, hardened leather over wooden boards. Its corners are reinforced with dull iron, and its spine is thick enough to endure years in a pack. Many surviving copies are stained with damp, mineral dust, dried fungus ink, candle smoke, and the grime of underground camps.
Inside, the book is densely written and heavily diagrammed. It includes sketches of drow tunnel-signs, edible and poisonous fungi, warning glyphs, cave-in fractures, patrol formations, climbing knots, underworld beasts, and cross-sections of common cavern systems.
Several chapters read less like instruction and more like warnings left by someone who expected most readers to die if they ignored a single sentence.
Marginal notes in later copies are common. Rangers, fugitives, scouts, escaped captives, and underworld guides often add local corrections, making some copies more useful than pristine editions.
Why This Item Matters
Most books about the world below are written by scholars who visited safe trade-caves and returned quickly. Footsteps Beneath was written from the other side of fear.
Its value lies not in magic, but in experience. It teaches how sound carries through stone, how to read damp air, how to avoid false roads, how to sleep without surrendering one’s life, and how to recognise the difference between an empty passage and a watched one.
The book is useful because it is specific. It does not promise mastery of the Underdeep. It teaches the first lesson of underground travel: assume the world below has already noticed you.

Training Manual
If you spend at least 40 hours studying Footsteps Beneath during downtime, you may use the book as a specialised trainer for Survival checks related to the Underdeep, Underdark, deep caverns, subterranean wilderness, drow territory, and similar lightless underworld environments.
The book does not grant proficiency automatically. Instead, it allows a character to justify training in the Survival skill without needing a living instructor, provided the campaign uses downtime training rules.
A character who already has proficiency in Survival may also study the book to sharpen their underworld fieldcraft. After completing the required study, the character gains advantage on one future Survival check made in the Underdeep or a similar subterranean wilderness. The check must directly relate to information covered by the book, such as reading tracks, finding water, judging tunnel safety, avoiding natural hazards, identifying edible fungi, choosing a safe campsite, or recognising signs of drow passage.
Once this advantage is used, the character must spend at least 1 hour reviewing the relevant section before gaining this benefit again.
Strict Limit
The lessons in Footsteps Beneath apply only to subterranean wilderness survival. They do not help with surface travel, forests, deserts, mountains, swamps, oceans, cities, or ordinary overland navigation.
The book is also not a complete guide to drow society, magic, politics, or religion. It teaches how to survive drow territory and recognise drow fieldcraft, not how to understand every secret of their civilisation.
Optional Rule: Hard-Won Lessons
If a character studies the book during an active underworld expedition rather than in safe downtime, the required study time may be reduced to 20 hours, but only if the character is applying its lessons in dangerous subterranean conditions.
This study must occur over several rests, watches, or camp periods. It cannot be rushed in a single sitting.

Description
A character who studies Footsteps Beneath may use it as a specialised trainer for the Survival skill, but only for Survival training connected to the Underdeep or similar subterranean wilderness environments.
The book does not grant skill ranks or skill points by itself. A character must still spend skill ranks or skill points normally when gaining a level. However, for the purpose of training, instruction, or downtime justification, Footsteps Beneath may replace a living trainer for increasing Survival up to 8 ranks, provided those ranks represent underworld survival training.
The lessons in Footsteps Beneath concern only survival in the Underdeep and similar underground wilderness regions. The book provides no benefit for Survival checks made on the surface.
Optional Pathfinder / 3.5e Downtime Rule
If using downtime training, studying Footsteps Beneath for at least 1 week allows a character to count the book as a qualified trainer for Survival, up to 8 ranks, but only for underground environments.
At the GM’s discretion, after completing this study, the character may gain a +2 circumstance bonus on one Survival check made in the Underdeep or similar subterranean terrain. This bonus applies only to checks involving navigation, tracking, finding food or water, avoiding natural hazards, identifying signs of drow movement, recognising edible fungi, or choosing safe campsites underground.
After the bonus is used, the character must spend at least 1 hour consulting the book before gaining this benefit again.

Author Greg Lynch, J. C. Alvarez
Publisher Mongoose Publishing
Publish date 2005
This thick tome was written by a high elf warrior and wizard named Feldefalas Arnion. The sole survivor of a drow attack on his village, Feldefalas devoted the remainder of his long life to hunting and killing the dark elves. He spent decades in the Underdeep, learning the ways of that alien world beneath the surface, putting his hard-won knowledge to use in his eternal quest for vengeance against the drow.
Eventually, he came to understand the Underdeep as well, or even better, as those who called the labyrinthine depths home. How many drow he slew in his centuries of personal war is unknown, but even the drow eventually came to fear him. The hunting parties they dispatched into the wilds of the Underdeep to find Feldefalas returned empty-handed, if at all, and the lone elf’s slaughter continued. Feldefalas eventually grew old enough that he could no longer continue his war, and retired to the surface, where he penned Footsteps Beneath, hoping the lessons he had learned would allow others to continue his struggle.
Anyone who studies Footsteps Beneath may use the information in the book to train his Survival skill up to eight ranks. The book does not grant the reader any skill points, he must spend his own points if he wishes to increase his skill, but it does effectively take the place of a trainer. Feldefalas lessons centre entirely on Survival in the Underdeep, the information contained in Footsteps Beneath is of no use to those on the surface.

How It Is Used
Adventurers use Footsteps Beneath before descending into the underworld, often reading it by candlelight in the days before an expedition. Wise parties assign the book to whoever is most likely to lead the march, read tracks, choose campsites, identify edible fungi, recognise ambush signs, or make the final decision about whether a passage should be entered at all.
In play, the book works best as a grounding item. It gives the party a believable reason to prepare for subterranean travel and helps distinguish the Underdeep from ordinary wilderness.
It can also serve as a narrative object. The party might find a copy in a dead scout’s pack, a sealed elven archive, a drow trophy-room, a ranger lodge, a smuggler’s cache, or the belongings of someone who reached the deep places and never returned.
Failure, Risk, and Misuse
Footsteps Beneath is not a guarantee of survival. It was written by someone who knew the Underdeep through danger, loss, hunger, and war. Its advice can be severe, suspicious, and sometimes ruthless.
Outdated Routes: Some maps and tunnel signs may describe passages that have collapsed, flooded, been claimed by monsters, or been deliberately altered by drow patrols.
Obsessive Bias: The book treats the Underdeep as hostile by default. That caution saves lives, but it may also make readers suspicious of possible allies, neutral settlements, or strange underworld customs they do not understand.
False Confidence: A surface traveller who has read the book may believe they understand the Underdeep. The book teaches survival, not mastery.
Dangerous Possession: Drow nobles, assassins, patrol captains, or underworld slavers may recognise the tome and treat its owner as a trained enemy rather than an ordinary trespasser.
Value in the World
A clean, complete copy of Footsteps Beneath is valuable to rangers, scouts, underworld caravans, escaped slaves, monster hunters, military commanders, elven houses, and surface realms threatened by drow raids.
Its ordinary listed price is 175 gp, but in the right hands it may be worth far more. In frontier towns above deep cave networks, copies are often locked away rather than sold openly. Some surface rulers consider the book too dangerous for common circulation, fearing it will encourage reckless expeditions into the world below.
Drow agents may pay well to destroy copies, identify who owns them, or replace them with altered editions containing fatal advice.
Trade, Copies, and Common Variants
- Standard Copy: A heavy copied folio containing the main text and diagrams. This is the usual 175 gp version.
- Field Copy: A shortened, weatherproofed version written on treated parchment or thin vellum. It is lighter, rarer, and usually more expensive than the standard copy.
- Annotated Ranger Copy: A working copy filled with notes from later underworld travellers. These may be especially useful, but some annotations may be wrong, local, or dangerously outdated.
- Elven Archive Copy: A carefully preserved version kept in a noble house, military archive, or old border fortress. These copies often include additional maps, casualty lists, patrol notes, or warnings against specific drow houses.
- Drow-Censored Copy: A captured version with certain sections removed, altered, or trapped with false marginalia intended to mislead surface scouts.
Using Footsteps Beneath in Your Game
Footsteps Beneath is strongest when the campaign treats the underworld as a hostile wilderness rather than a simple dungeon backdrop. It gives players a practical tool, but not a shortcut. The book should help them ask better questions, prepare more intelligently, and notice dangers they might otherwise miss.
Use it to support scenes involving expedition planning, drow pursuit, underworld navigation, survival pressure, dwindling supplies, or the dreadful realisation that the party has entered a region where surface instincts no longer apply.
The book should not remove danger. It should make danger more legible.
Adventure and Worldbuilding Hooks
- The Last Marginal Note: A copy of the book contains a handwritten note pointing to a hidden refuge deep beneath a dead elven kingdom.
- The Drow Want It Burned: A drow house sends assassins after anyone carrying a complete copy of Footsteps Beneath.
- The False Chapter: One widely circulated copy contains a forged chapter that leads readers into an ambush site.
- The Old Hunter’s Route: The book describes a secret trail through the Underdeep that bypasses a fortified drow city, but the route has not been used in generations.
- The Survivor’s Debt: An elderly scout recognises the book and insists that one important lesson was deliberately omitted from most known copies.
- The Living Edition: A newly discovered copy contains fresh annotations written in an unknown hand, describing tunnels that did not exist when the original text was copied.
