✦ The Global Bazaar

Skip prep burnout. Play your first session tonight.

The #1 reason exciting D&D campaigns fizzle out is prep fatigue: spending 30 hours drawing maps, building stat blocks, and sweating over lore before dice even hit the table.

The Bazaar is engineered specifically for new and time-strapped Dungeon Masters. Browse a living marketplace of community-created adventures, drop-in dungeons, populated taverns, and bespoke NPC packs. One click imports everything directly into your campaign — fully formatted with @mentions, map pins, and Codex cards.

"I was terrified to DM my first session. I grabbed a ready-made tavern and mystery from the Bazaar, and my players thought I had been worldbuilding for weeks." — Sarah T., First-time DM

✦ Interactive Cartography

When players derail the plot, keep your world at your fingertips.

Every Game Master knows the dread: the party suddenly ignores your quest hook and heads into the untamed eastern spine, asking "What's over those mountains?"

No more awkward pauses or flipping through binders while combat stalls. Pin every city, ruin, NPC hideout, and territorial border onto high-resolution world and battle maps. Click any marker for instant lore, secret DM notes, and tactical stats without breaking immersion.

✦ Instant Interactive Tour

Want to explore the live app before registering?

Launch The Sunken Vault of Karas — a complete 1st-level starter one-shot built on the D&D 5e SRD 5.1 (CC-BY-4.0) with tactical maps, interactive pins, story notes, and Codex cards.

✦ The Story Board

A campaign can't be conquered — forgetting details can.

Scattered Google Docs, lost Discord scraps, and spiral notebooks with faded ink are where grand campaigns go to die.

The Story Board gives you a distraction-free binder for grand story arcs, weekly session recaps, and hidden conspiracy notes. Use smart @Gothma GOTHMA NPC Luitanant in the Ogroid's Crucible to link characters, artifacts, and factions directly into your prose. Hovering any mention opens a live reference card without leaving your text.

The Codex TCG Cards
✦ The Codex

Every entity presented like a collectible TCG card.

Say goodbye to boring text tables and soulless spreadsheets. The Codex turns your world's inhabitants, factions, monsters, and relics into tactile, collectible cards.

Filter instantly by entity type, status, or faction. Each card displays portraits, quick combat and roleplay stats, relationships, and child entities. Browsing your campaign feels as satisfying as opening a booster pack of your own imagination.

✦ Blueprint Architect

Reusable blueprints that save hours on every new entity.

Stop re-typing stat blocks and restructuring notes every time you create a new tavern, magic sword, or pantheon deity.

The Blueprint Architect lets you design customizable templates for any entity category. Drag and drop text fields, combat stats, artwork frames, and GM secrets into custom columns. Once created, spawn rich, perfectly structured entities in seconds with complete schema consistency.

Frequently Asked Questions

Everything you need to know about building, organizing, and running your tabletop campaigns in Nebula.

What makes Nebula different from other tabletop campaign managers?

Most tools are either blank documents (like Google Docs or Notion) with zero spatial context, or complex battle-grid VTTs with clunky note-taking. Nebula bridges the gap: it weaves your interactive maps, story binders, character codex, and custom blueprints into a live hierarchical web. Mention any character in your notes with @mention to inspect their stats instantly, pin them to a map landmark, or trace their faction allegiance without ever losing your train of thought.

Can my players join my campaign, and are my DM secrets safe?

Yes! You can invite your entire adventuring party with role-based permissions. Players can explore unlocked map landmarks, browse public lore in the Codex, view relationship trees, and update their own character blueprints. Any DM-only secrets—such as hidden map pins, secret dungeon chambers, monster stats, and private plot twists—remain completely locked and invisible to players.

Is Nebula free to use? What is included in the Starter tier?

Nebula provides a generous free Starter tier that grants you full access to all core world-building features: interactive cartography with pins, distraction-free story binders, custom character blueprints, and codex entries. Paid tiers (Adventurer, Professional, Divine) unlock unlimited campaigns, expanded storage, co-DM collaboration seats, interactive family trees, and monthly loyalty Platinum.

What is the Blueprint Architect? Can I use it for non-D&D systems?

The Blueprint Architect is our drag-and-drop layout engine. Instead of forcing you into a single rigid 5e character sheet, it lets you construct custom templates for NPCs, monsters, spells, magical items, vehicles, and faction dossiers using modular blocks (dice rollers, number modifiers, text blocks, image slots, dropdowns, and checkboxes). Whether you play D&D 5e, Pathfinder 2e, Call of Cthulhu, Cyberpunk RED, or your own homebrew ruleset, Nebula adapts to your table.

What is The Bazaar, and can I share or sell my campaign creations?

The Bazaar is Nebula's global creator marketplace. If you have crafted an intricate dungeon blueprint, a balanced homebrew monster pack, or an entire regional setting, you can publish it to the community. You can share your assets freely to earn Goblin Coins and climb creator rankings, or list premium content to earn Gold from fellow Game Masters.

Can I export my campaign notes to Obsidian or download offline backups?

Yes, your lore belongs to you. Nebula features a 1-click Obsidian Vault Export that packages your entire campaign into a clean `.zip` archive. It preserves your folder hierarchies, markdown files, image attachments, and bi-directional wikilinks ([[Entity Name]]) so you can read and edit your notes anywhere, even completely offline.

What is the Open Beta, and how do I claim the 1-year free subscription?

Nebula is currently in active Open Beta.
