“A ruin is never silent. Stone remembers pressure. Metal remembers fire. Magic remembers every command it was ever forced to obey.”
— Magister Thel Varun, Seventh Survey of the Hollow Vaults
Introduction
Deep Ruin Arcanists are scholars, sorcerers, ward-readers, relic specialists, and magical surveyors trained to investigate arcane remains in dangerous subterranean environments. They enter collapsed wizard-vaults, abandoned dwarven halls, buried temples, sealed laboratories, cursed caverns, and forgotten Underdark settlements where magic has persisted long after its creators vanished.
A Deep Ruin Arcanist is not merely an academic who studies old enchantments from the safety of a library. They are a field specialist who understands that ancient magic may be unstable, incomplete, corrupted, or still obeying instructions given centuries ago. They assess magical hazards, identify the purpose of ruined systems, record sigils and command structures, stabilize dangerous relics, and determine whether a site should be explored, sealed, cleansed, or destroyed.
Characters with this background are cautious without being timid, intellectually curious without being careless, and acutely aware that history can remain active long after everyone who remembers it is dead.
Description
The civilizations of Aetheris have left countless magical remnants beneath the earth. Some were buried deliberately. Others sank through collapse, war, planar upheaval, or geological change. Ancient roads descend into darkness beneath newer settlements. Sealed laboratories lie beneath fortress foundations. Dwarven transit engines continue to draw power from forgotten reservoirs. Elven wards protect chambers whose names have vanished from every surviving archive. Shadowfell seepage stains abandoned gates, while aberrant influence twists leyline currents into patterns no mortal architect intended.
Deep Ruin Arcanists are trained to interpret these places.
Their education combines formal arcane theory with practical exploration. Apprentices study magical notation, ritual architecture, ward geometry, planar resonance, relic classification, historic construction methods, and the signs of arcane contamination. They also learn how to crawl through collapsed passages, sketch structures under pressure, mark safe routes, preserve fragile inscriptions, and recognize when a magical system has begun reacting to their presence.
Many Deep Ruin Arcanists begin as members of academies, noble survey offices, arcane guilds, military engineering corps, religious archives, relic commissions, or private expeditions. Others are self-taught sorcerers whose innate magic allows them to sense patterns that formal scholars overlook. Draymari arcanists are especially respected for combining emotional discipline, force of personality, and intuitive magical awareness with rigorous field study.
The work demands humility. A rune may appear decorative but function as a targeting matrix. A sealed door may recognize bloodlines rather than keys. A subterranean lake may be an illusion covering a planar breach. A broken spell-engine may continue to perform one surviving function while every safeguard around it has failed. The most dangerous ruins are often not dead places, but systems still attempting to complete commands that no longer make sense.
Deep Ruin Arcanists maintain complicated relationships with treasure hunters, militaries, nobles, and collectors. Their expertise is highly valued, but their warnings are often inconvenient. A responsible arcanist may insist that an expedition abandon valuable relics, seal a promising chamber, or destroy an artifact rather than remove it. Greedy patrons sometimes dismiss such caution until the ruin begins answering them.
Many Deep Ruin Arcanists become adventurers because the greatest arcane sites cannot be studied from afar. Some seek lost knowledge. Some investigate a recurring magical disturbance. Others follow the trail of a stolen relic, search for the source of a family curse, or attempt to correct a disaster caused by an earlier expedition. A few have encountered something beneath the world that should never have awakened and now travel to ensure that its influence spreads no farther.
Whatever their motive, a Deep Ruin Arcanist enters forgotten places not simply to recover what remains, but to understand what is still happening there.

- Feat: Choose one of the following feats, subject to the rules used in your campaign:
- Magic Initiate: Wizard
- Observant
Magic Initiate represents formal training in basic arcane methods beyond your primary class. Observant reflects the disciplined attention required to identify faint inscriptions, hidden mechanisms, irregular patterns, and environmental changes.
At the Game Master’s discretion, the following feats may also be appropriate:
- Ritual Caster: Wizard
- Dungeon Delver
- Skilled, with proficiencies related to History, Perception, tools, or additional scholarly expertise
- Skill Proficiencies: You gain proficiency in the following skills:
- Arcana: You studied magical theory, ward construction, relic behavior, planar effects, sigils, curses, and the signs of unstable spellwork.
- Investigation: You learned to reconstruct events from damaged environments, examine mechanisms, identify inconsistencies, and distinguish meaningful details from ruin debris.
- Choose one of History or Perception: History represents your knowledge of lost civilizations, architectural traditions, and the development of arcane systems. Perception represents field training in noticing faint sigils, pressure changes, magical distortions, structural instability, and subtle environmental warnings.
- Tool Proficiencies: Deep Ruin Arcanists must document what they discover and preserve information that may vanish after a site collapses, shifts, or becomes inaccessible.
You gain proficiency with:
- Cartographer’s Tools
- Calligrapher’s Supplies
Cartographer’s tools are used to map passages, mark ward boundaries, record elevation changes, and note magical danger zones. Calligrapher’s supplies are used to copy sigils, reproduce inscriptions, create rubbings, compare scripts, and preserve damaged magical notation.
At the Game Master’s discretion, a character associated with an engineering, mining, or military institution may replace one of these proficiencies with Tinker’s Tools or Mason’s Tools.
- Languages: Your studies exposed you to magical traditions, subterranean civilizations, and technical inscriptions written in languages rarely used in ordinary conversation.
You can speak, read, and write two languages of your choice, commonly selected from:
- Undercommon
- Draconic
- Dwarvish
Other appropriate choices may include Elvish, Infernal, Primordial, or a regional language associated with the ruins you studied.
- Equipment: You begin with the following equipment:
- Durable expedition clothing or divided travel robes suited to subterranean movement
- A crystal inspection lens
- A ward-marking stylus
- Cartographer’s tools or calligrapher’s supplies
- A small case containing powdered silver, chalk, charcoal, and mineral pigments
- A field journal filled with ruin sketches, sigil rubbings, hazard notes, and unfinished theories
- Several sheets of parchment and a vial of waterproof ink
- A small sample case containing harmless fragments of crystal, tile, wire, or engraved stone
- A hooded lantern or crystal light
- A personal token recovered from your first ruin
- A pouch containing 15 gp
Your personal token might be a damaged command plate, a piece of inert wardstone, a cracked lens, a fragment of ancient script, or an object whose purpose you have never been able to determine.
The ruin that shaped your training remains central to your identity. Roll on the Defining Ruin table or choose the result that best fits your character.
| d8 | Defining Ruin |
|---|---|
| 1 | Collapsed Wizard-Vault. You survived a vault whose defensive systems continued to attack anyone unable to answer questions in a forgotten language. |
| 2 | Abandoned Dwarven Engine Hall. You studied an immense subterranean mechanism that still draws power, though no one understands what it was designed to operate. |
| 3 | Buried Temple. You explored a shrine whose rituals altered the surrounding stone and continued long after its worshippers disappeared. |
| 4 | Planar Breach Site. You witnessed a place where another plane had seeped into the earth, changing gravity, memory, light, or time. |
| 5 | Aberrant Excavation. You investigated ruins modified by an intelligence whose symbols hurt to understand and whose machinery may have been grown rather than built. |
| 6 | Shadow-Stained Road. You surveyed an ancient underground route touched by the Shadowfell, where travelers sometimes meet echoes of journeys that never happened. |
| 7 | Sealed Arcane Laboratory. You entered a research complex where unfinished experiments continued to alter the environment. |
| 8 | Living Ruin. You discovered a site that reacted to visitors, rearranged its own passages, or appeared to possess memory and intent. |
Ward-Sense Surveyor
You are trained to recognize the physical, structural, and magical signs left by old enchantments, defensive systems, rituals, and arcane infrastructure.
When you spend at least 10 minutes examining an ancient structure, buried complex, magically altered cavern, sealed chamber, ruined shrine, abandoned laboratory, or similar location, you can usually determine the broad nature and intended function of any obvious magical systems associated with the site.
You may be able to identify whether the lingering magic is primarily:
- Protective
- Destructive
- Ritualistic
- Illusory
- Necromantic
- Planar
- Aberrant
- Elemental
- Communicative
- Containment-based
- Transportation-related
- Connected to old infrastructure
You can also often determine whether a visible magical system appears stable, damaged, dormant, corrupted, depleted, overloaded, or still actively receiving power.
Examples of old magical infrastructure include:
- Arcane gates
- Lifts and moving platforms
- Warded doors
- Reservoirs
- Defensive circles
- Spell-engines
- Sealed vaults
- Communication arrays
- Environmental regulators
- Ritual chambers
- Magical lighting systems
- Planar anchors
- Containment fields
This feature does not automatically reveal hidden magic, identify a specific spell, provide command words, disable magical traps, or make dangerous relics safe to handle. It instead gives you a reliable interpretive advantage. You understand what kinds of questions should be asked before someone touches, opens, removes, or activates something.
The Game Master may provide your conclusions through visual signs, arcane residue, changes in pressure, resonant vibrations, recurring glyph structures, heat, light, distortion, emotional impressions, or the reactions of your own magic.
Powerful concealment, unfamiliar extraplanar systems, deliberate sabotage, or technologies outside your experience may limit what you can determine.
Surveyor’s Markings
You know a standardized system of field markings used by ruin scholars, magical surveyors, and responsible expedition crews.
Using chalk, charcoal, ink, powdered silver, scratched lines, or arranged stones, you can mark:
- Safe routes
- Explored passages
- Unstable structures
- Magical hazards
- Active wards
- Dead ends
- Contaminated areas
- Possible exits
- Places requiring silence
- Objects that should not be touched
- Areas that have changed since the last survey
Creatures familiar with arcane expeditions, military delving, scholarly surveys, or subterranean rescue work may recognize your markings and understand their general meaning.
Your marks are not secret and can be altered, erased, or imitated. They do not create magical protection. However, a properly marked route allows a group retracing your path to understand the dangers you observed and reduces the likelihood of accidental interference with previously identified hazards.
When navigating a ruin you have personally surveyed and marked, you can usually retrace your route without becoming lost unless the structure has changed, magic has altered the path, or your markings have been removed.
Suggested Characteristics
Deep Ruin Arcanists are shaped by curiosity, discipline, danger, and the knowledge that one careless action can awaken threats buried for centuries.
| d6 | Personality Trait |
|---|---|
| 1 | I inspect doors, floors, ceilings, and inscriptions before allowing anyone to proceed. |
| 2 | I record every discovery, even when others insist that it is unimportant. |
| 3 | I become visibly irritated when someone touches a relic before I have examined it. |
| 4 | I explain magical hazards with precise technical language, especially when frightened. |
| 5 | I maintain deliberate personal rituals because order helps me control uncertainty. |
| 6 | I am fascinated by dangerous magic, though I would never admit how strongly it draws me. |
| d6 | Ideal |
|---|---|
| 1 | Understanding. Ignorance turns every ruin into a weapon. Knowledge is the first protection. (Neutral) |
| 2 | Restraint. Not everything that can be opened should be opened. Not everything that can be used should be used. (Lawful) |
| 3 | Preservation. Lost knowledge belongs to the future, not merely to the first person strong enough to seize it. (Good) |
| 4 | Mastery. Magic becomes dangerous when fear prevents us from understanding it. (Any) |
| 5 | Responsibility. Those who awaken ancient powers are obligated to contain the consequences. (Lawful Good) |
| 6 | Freedom. No magical system should be used to enslave minds, souls, bloodlines, or entire peoples. (Chaotic Good) |
| d7 | Bond |
|---|---|
| 1 | I carry a relic from the first ruin I explored, and I still do not understand its purpose. |
| 2 | A mentor disappeared while investigating a sealed complex. I intend to find out what happened. |
| 3 | I accidentally activated an ancient system that harmed others, and I will correct that mistake. |
| 4 | My academy, guild, or patron funded my training, and I still owe them discoveries, service, or loyalty. |
| 5 | My academy, guild, or patron funded my training, and I still owe them discoveries, service, or loyalty. |
| 6 | I know the location of a ruin that must never fall into the wrong hands. |
| 7 | An ancient ward responded to me as though it recognized my blood, name, or magic. |
| d6 | Flaw |
|---|---|
| 1 | I become so focused on an arcane problem that I ignore immediate physical danger. |
| 2 | I assume untrained companions will mishandle anything important. |
| 3 | I conceal discoveries when I believe others are too reckless to be trusted with them. |
| 4 | I find it difficult to destroy magical knowledge, even when preservation is clearly dangerous. |
| 5 | I am privately convinced that I can understand any magical system if given enough time. |
| 6 | 6. When my warnings are ignored, I may become cold, vindictive, or unwilling to help those responsible. |
Contacts
Your contacts may include academy instructors, expedition sponsors, ward engineers, relic conservators, dwarven archivists, military surveyors, Underdark guides, arcane cartographers, mineral scholars, and specialists who study particular civilizations or forms of magic.
These contacts can provide historical records, maps, translated inscriptions, basic magical supplies, introductions to institutions, or information about newly discovered sites. Some may offer laboratory access or secure storage for dangerous relics. Others may seek your judgment before authorizing excavation, salvage, settlement, or military occupation of an ancient complex.
Your relationships are often professional, competitive, and strained by disagreement. Ruin scholars frequently dispute interpretations, ownership, publication rights, and the proper handling of relics. A respected mentor may admire your instincts but criticize your lack of caution. A rival may challenge your conclusions while secretly relying upon your work. A patron may value your expertise until your recommendations threaten their profit.
You may also know expedition workers who rarely receive scholarly recognition: porters, miners, rope specialists, lantern keepers, scouts, translators, healers, and survivors. Experienced Deep Ruin Arcanists understand that these individuals often notice hazards long before senior academics do.
Treasure hunters, relic smugglers, cultists, slavers, and arcane coercers may regard you as an obstacle. Institutions seeking to weaponize ancient magic may attempt to recruit, bribe, discredit, or silence you.
