Summary

Plot Overview

The Lost Library of Lethchauntos is a scholarly expedition-turned-dungeon crawl in which the party is recruited to locate (or reclaim) a long-lost arcane library hidden beneath dangerous, forgotten ruins. As they descend through layered chambers filled with magical traps, constructs, and rival interests, the adventurers piece together the fate of the library and its enigmatic creator. The adventure blends exploration and puzzle-solving with combat, culminating in a confrontation that determines whether the knowledge within is preserved, exploited, or destroyed.

Key Elements

  • Central Mystery & Lore Hook– The adventure revolves around the disappearance of the legendary mage Lethchauntos and the hidden location of his vast, knowledge-rich library, drawing the party into a quest driven by curiosity, scholarship, or power.
  • Layered Dungeon Exploration – The library is buried beneath ancient ruins, featuring multiple levels that progressively reveal history, danger, and magical complexity, rewarding careful exploration and attention to detail.
  • Arcane Traps & Puzzles – The environment is heavily warded with magical defenses, riddles, and mechanisms that reflect the intellect of its creator, emphasizing problem-solving over brute force.
  • Guardians & Opposition Forces – The party encounters enchanted constructs, magical entities, and possibly rival factions or treasure-seekers, creating both combat and social tension.
  • Moral/Outcome Choice – The climax hinges on what the party decides to do with the library’s knowledge—preserve it, claim it, share it, or destroy it—impacting future storylines and consequences in the campaign world.

Themes

  • The Preservation vs. Control of Knowledge – The library represents immense arcane knowledge, raising the question of whether such power should be safeguarded, shared, or controlled—highlighting the responsibility that comes with discovery.
  • Curiosity and Consequence – The pursuit of hidden truths drives the adventure, but every revelation carries risk, reinforcing the idea that seeking knowledge can lead to both enlightenment and danger.
  • Legacy of the Past – The ruins and the fate of Lethchauntos reflect how the ambitions of powerful figures endure beyond their lives, shaping the present and forcing the players to confront the lasting impact of history.

NPC

NameDescriptionDM Notes
Archivist Selvara ThennA determined and scholarly sage who hires or guides the party, obsessed with recovering lost knowledge from Lethchauntos’ library.She can serve as the quest-giver and moral compass, but may secretly prioritize preservation over safety—potentially pressuring the party to take risks.
The Custodian ConstructAn ancient, sentient construct designed to protect the library, still faithfully executing its creator’s directives.Use it as a recurring guardian—initially hostile but potentially reasoned with if the party demonstrates respect for knowledge or solves key puzzles.
Rival Seeker Malrec VossA cunning treasure-hunter or mage who seeks the library for personal gain, often appearing just ahead of or behind the party.Introduce tension through competition; he can become a temporary ally or final antagonist depending on how the party interacts with him.

Organizations

OrganizationDescriptionDM Notes
The Collegium ArcanumA formal order of mages and scholars dedicated to preserving magical knowledge and recovering lost artifacts.They are the most “legitimate” faction; they may sponsor the party but will expect control over any discoveries—creating tension if players want independence.
The Obsidian HandA secretive faction seeking powerful arcane secrets for influence, profit, or domination.Operate through agents and intermediaries; they may already have spies inside the ruins or be backing a rival NPC like Malrec Voss.
Keepers of the VeilA small, quasi-religious group that believes certain knowledge is too dangerous to exist.They act as ideological opposition—potentially sabotaging access to the library or urging the party to destroy what lies within.
(Optional) Free Delvers ConsortiumA loose network of treasure-hunters and explorers who share rumors of lost sites.Useful for rumors, side quests, and introducing competition without a single clear antagonist.

DM Information

We are using the Wizards of the Coast latest Companion to track our play. This is mostly a Magic: the Gathering tool & it would be nice to have a sperate D&D App or at list a choice of screen branded for the worlds greatest role playing game!

I am using table stands to remind the players of some critical information–classes of players at the table, adventure name, and party name. We named the party Front Entry Door after a very annoying employee back room alarm on the shops front door that plagued us during our first session!

Here is a video of my DM notebook for this campaign. It is from Fieldnotes.

The Fieldnotes D&D DM notebook is fun, but what I really need is more organized initiative tracking with conditional effects and notes easily editable
