Besides this website, JDR Ninja publishes a game system and modules for Foundry VTT. You install them directly from Foundry.

MGT2

The system for playing Mongoose Traveller, 2nd edition, in Foundry VTT.

Game system Foundry V14 Free Apache 2.0 license

MGT2 handles a whole campaign: roll requests to the entire table, damage with armour and recovery, group character creation, space combat, travel and jumps, trade and ship finances. It contains no text from the books, which you still need to play.

Retro CRT Terminal

Fictional computer terminals styled as cathode-ray screens, which your players browse with the keyboard.

Module Foundry V14 Free MIT license

Interface languages: French and English

Each terminal is a journal whose pages become screens. You reveal entries as the game goes on, lock some of them and choose a CRT or VHS theme. The GM can show the same screen to every player, or let them open the published terminals. The module includes a guide in French and English, with templates and macros.

Module Foundry V14 MIT license

Document Data Explorer

A GM tool to read and fix the data of any Foundry document.

Module Foundry V14 Free MIT license

Interface languages: French and English

It adds a command to every sheet that opens its data as a tree, with the type of each field. You compare the stored value with the one the system computes, then apply your corrections in a single update. It is useful for preparing a macro or a Stream Deck command, or for repairing a value that a macro broke.

Document Data Explorer open on a character: the data tree, the type of each field and a value brought back by the system from 99 to 24

Install a system or a module

  1. On Foundry VTT's setup screen, open the Game Systems tab for MGT2, or the Add-on Modules tab for the other three.
  2. Click the install button, then search for the name of the system or module in the list.
  3. Install it. A system is chosen when you create a world; a module is enabled in the world's module management.

If the module does not appear in the search, paste its manifest URL into the install window. Foundry then installs the latest published version and keeps it up to date like any other.

Frequently asked questions

Which version of Foundry VTT do I need?

Foundry VTT version 14 or later, for all four.

What if Foundry cannot find a module?

Paste its manifest URL, given on this page, into Foundry's install window. The module then updates like those in the list.

Is MGT2 an official Traveller system?

No. MGT2 is an unofficial system, not affiliated with Mongoose Publishing. It contains no text from the books: you need the Mongoose Traveller, 2nd edition rules to play.

Are these modules free?

Yes, all four are free to install. MGT2, Retro CRT Terminal and Document Data Explorer work without a JDR Ninja account. In the JDR Ninja module, Stream Deck commands are free; the D&D generators, sending rolls to the overlay and Atlas synchronization require a subscription.

Where do I report a problem?

On each module's source code page, in the “Issues” tab on GitHub. Include your Foundry version, the module's version and the steps that lead to the problem.
