Answers from the Ancestors
Frequently asked questions from architects across the multiverse.
What is the best campaign manager for D&D and tabletop RPGs?
Nebula Command is engineered specifically to solve the organizational chaos Dungeon Masters face. By combining hierarchical world-building, interconnected relationship maps, and intelligent timeline tracking, Nebula serves as the ultimate, all-in-one campaign manager for D&D 5e, Pathfinder, and custom tabletop systems.
How to organize my D&D campaign notes effectively?
Stop flipping through dozens of loose notebooks or unstructured documents. Nebula uses a Hierarchical Cartography architecture, meaning you can tie an NPC directly as a child of a Location, and link that Location to a Faction. Everything is easily accessible in a structured tree, keeping your world perfectly synchronized.
Can I customize rulesets and character sheets?
Yes! Nebula comes equipped with the Hero's Forge. You can define custom mechanics, stats, and blueprints tailored precisely to your homebrew setting. When your players discover a new artifact or confront a custom monster, you can manage them seamlessly through your uniquely designed templates.
Can I share or sell my campaign creations with others?
Absolutely. Nebula features a thriving global 'Bazaar'. If you've crafted an incredible magical item, an intricate dungeon map, or an entirely new custom ruleset, you can publish it to the community. You can earn Goblin Coins for free contributions or Premium Gold if players deeply value your premium creations.
