Compendium
Keep documents, images, handouts, maps, and other source material together. Every Realm has its own Compendium and its own Canon.
A TTRPG worldbuilding tool for long-running campaigns
Atlavium
Organize game master notes, maps, people, places, Quests, Sessions, and Canon in private Realms. Atlavium turns scattered campaign knowledge into a connected worldbuilding archive you can search and keep using at the table.
Worldbuilding and campaign management work without AI. Keeper is optional and currently enabled on request through Discord.
One account, many Realms
Your world is more than a folder of notes.
People, places, factions, events, Sessions, and sources belong together. Atlavium keeps those links visible and searchable while every Realm stays a separate private workspace with its own Compendium and Canon. Think of it as a private campaign wiki built for connected RPG worldbuilding, not a public directory.
Whole-Realm searchFind notes, entities, Quests, Sessions, and images from one search.
A clear CanonConnect claims to sources and decide which version belongs in your world.
Flexible structureChoose your own entity types, categories, relationships, and calendar.
Connected worldbuilding
Build the world, then keep its connections usable.
Atlavium joins the knowledge of your world with the history of play. Your Compendium, maps, World Entities, sources, calendar, Campaigns, Quests, and Sessions remain separate tools, but they can point to one another.
Compendium and connected world knowledge
Give people, places, factions, maps, events, and sources a reliable home. Structure can grow with the world instead of forcing it into one fixed ruleset.
Maps and Whiteboards
Place maps, sketches, preparation notes, and linked content on a free canvas when spatial context explains more than another paragraph.
Realm Calendar
Use an existing calendar or configure one for your setting, including months, weekdays, holidays, travel, moons, and dated events.
Configurable World Entities
Create structured entries for people, places, factions, kingdoms, artifacts, or your own entity types instead of flattening everything into documents.
Your types, icons, and colors
Shape categories and World Entity types around the setting so even a large Realm remains legible and searchable.
Relationships and World Graph
Connect World Entities through current Relationships and inspect the wider structure in the World Graph.
Sources and traceable facts
Record dated World Events and attach evidence so the history behind a Relationship remains understandable years later.
From worldbuilding to the table
Campaign management belongs beside the world, not above it. Prepare Sessions, follow Quests and Campaigns, preserve recaps, and search the full play history later.
Campaigns
Organize longer story arcs without treating the Campaign as the whole Realm. A Realm can hold several Campaigns and independent Quests.
Quests
Keep goals, open threads, tasks, and optional side paths visible before and after the group decides to ignore the obvious plot.
Sessions and recaps
Prepare the next real play Session, record its date, and preserve what the group experienced, decided, or missed.
Search the whole Realm
Find game master notes, entities, images, Quests, and Sessions with filters instead of remembering which folder held the clue.
From worldbuilding to the table
Keep preparation, play, and long-term history in one useful loop.
- Bring established Canon into the Compendium as documents, images, maps, World Entities, and sources.
- Connect people, places, factions, Relationships, and World Events in the World Graph.
- Organize active play with Campaigns and Quests, then prepare the next Session and write its recap.
- Use Realm search at the table and return to the same campaign knowledge months or years later.
What Atlavium is not
Knowledge around your table, not a replacement for it.
Atlavium preserves the knowledge, Canon, and play history around your table and complements the tools you already use.
No virtual tabletop and no live combat simulator.
No rules automation and no character sheet manager.
No generic AI world generator. The world and its Canon remain yours.
Optional, source-grounded assistance
Ask Keeper. Keep the final word.
Keeper works from the contents of your current Realm. It helps you retrieve and summarize what you recorded, points to relevant sources, and can surface connections, gaps, or possible contradictions. It may suggest what to explore next, but you decide what becomes Canon.

A sourced Keeper answer
What connects Waldemar to Evelyn?
One confirmed World Event records Waldemar’s oath at the Ash Bridge with Evelyn as a witness. Session 18 and an open Quest provide the play context. The sources do not establish a closer relationship, so Keeper marks that as an inference rather than Canon.

What Keeper can help with
Grounded in the current Realm
Keeper searches the documents, World Entities, Sessions, Quests, images, and calendar of the Realm you are working in. Other Realms stay outside that context.
Sources stay visible
Open the material behind an answer and check whether a statement is recorded, disputed, incomplete, or only an inference.
Suggestions, not Canon
Keeper can summarize, rephrase, and propose connections. Nothing becomes part of your Canon until you review and apply it.
Retrieve documents, World Entities, Sessions, Quests, and images Summarize established campaign knowledge with its sources Distinguish current Relationships from dated World Events Point out gaps and possible contradictions Support Session preparation without deciding the Canon
Would Keeper help at your table?
Keeper access is currently enabled on request. Ask on Discord, tell me a little about your group, and try it only if optional AI support fits your way of working.
Privacy and sharing
Private Realms, deliberate connections
Your content stays yours and is not used for general AI training. Realms remain separated, and neither a Fellowship nor a link silently opens a private Realm.
Realms stay separate
Content and Keeper context belong to the current Realm. Other Realms are not mixed into it.
Fellowship is not access
A Fellowship is an invite-only connection between accounts. It does not grant access to either Realm.
Share selected content
You choose which content or bundle to hand over and can review what travels before it reaches another Realm.
End a share
A share can be revoked. Atlavium does not make public Realm directories the default.

Still unsure? Ask on DiscordWhat is Atlavium?
Atlavium is a cloud-based TTRPG worldbuilding tool for game masters, worldbuilders, and players. It connects documents, images, World Entities, Campaigns, Quests, Sessions, calendars, Whiteboards, search, and the World Graph. You can use it like a private campaign wiki, but with structured relationships and play history instead of isolated pages.
Is Keeper the same thing as Atlavium?
No. Atlavium is the complete product. Keeper is its optional, source-grounded AI librarian. Core RPG worldbuilding, campaign management, game master notes, search, and play tracking work without Keeper.
Can I start for free?
Yes. Registration is open, and the service is currently free. You can create an account in your browser and start a Realm. Keeper features are enabled separately on request through Discord.
Which roleplaying systems does Atlavium support?
Atlavium is system agnostic. Use it for Dungeons & Dragons, Pathfinder, The Dark Eye, another published system, or your own setting. It organizes campaign knowledge and world structure instead of automating one ruleset.
Is Atlavium a virtual tabletop or character builder?
No. Atlavium does not move tokens, simulate live combat, automate rules, or manage character sheets. It preserves the knowledge, Canon, and play history around your table and complements the tools you already use.
What is a Realm?
A Realm is one private, separated world and workspace with its own Compendium, Canon, calendar, content, settings, and history. One account can hold several Realms without mixing their data.
Who decides what becomes Canon?
You do. Keeper can retrieve sources, summarize what is recorded, and point out connections or possible contradictions. Its suggestions do not become Canon until you review and apply them.
Is my content used to train AI models?
No. Your content is not used for general AI training. If you activate Keeper, relevant material from the current Realm is processed to answer and assist you. Other Realms stay outside that context.
Does a Fellowship give somebody access to my Realm?
No. A Fellowship is an invite-only connection between accounts, not permission to enter a Realm. You choose selected content or bundles to share, and a share can be ended again. Private Realms are not placed in a public directory by default.
