A worldbuilding companion for game masters
WildMagic helps you tie up last session's loose threads, prep the next one, and get everyone to the table.
Sign up for early accessMost worldbuilding tools are wikis. WildMagic is built for the way GMs actually run games: a single canonical world underneath, and a living layer of campaign-specific overrides on top — so what your party did to House Ashcroft doesn't quietly rewrite the world for the next group.
— 01
World, then campaigns
Define a world once. Run as many campaigns inside it as you want. Each campaign gets its own divergent timeline without polluting the canon.
— 02
Quiet GM notes
Every entity has a hidden GM layer — secrets, motivations, long-term plans. Players never see them. You never lose them.
— 03
Connections, not folders
NPCs link to factions link to events link to locations. Trace a thread in either direction. Find the consequences before your players do.
Worldbuilding is intimate. We'd rather build the right thing with a small group of GMs than the wrong thing at scale. Here's where we are, what's stable, and what's not.
