High Guard Rules

StarCar is a permanently free linear star systems cartography tool. It enables GMs running sci-fi campaigns to visualize and share star maps with their players easily. It allows a lot of different customizations for orbital bodies, like planets, secondary stars, Ringworlds, Dyson Spheres, and more. GMs can add notes to individual orbital bodies, stars, and moons. The notes can be totally customizable, or use either Traveller or Stars Without Number rules. If they want, the GM can even export a stylized PDF report that details all the notes in an easy-to-follow format. And if the GM just needs something right away? StarCar will roll the dice and generate a totally randomized system: random stars, planets, and even randomized plot hooks. Once the GM is finished, they can export it in a number of different formats: PNG, WebP, or JPG, or with settings like Printer Friendly or Transparent Background. Anything exported is licensed under Creative Commons 4.0, which means the person who makes it owns it. They can even use it in any products they sell, with attribution.

Nav-Fi³ is a web-based campaign companion for the Traveller RPG, covering both the classic Third Imperium setting and Mongoose's 2300AD. Run your ship like a real operation: a time-aware financial ledger tracks income, costs, mortgages, and crew payroll against each vessel's account, with automatic PENDING/POSTED transitions synced to your campaign's calendar. Plot jump routes on an interactive TravellerMap-integrated navigator, manage cargo holds and speculative trade, and let The Cube (or 2300AD's The Link) generate freight, passenger, mail, salvage, and prize contracts on demand. Multi-user by design: a Referee can grant players granular access to piloting, cargo, or finance on a per-ship basis, suspend and reinstate them without touching the roster, and everyone logs in with Google or Discord (2FA supported). Crew records track status over time — active, MIA, deceased — and every session's changes surface in an automatic "Since Last Session" recap. Two settings, one interface: pick Traveller (with full Milieu/era support) or 2300AD (Gregorian calendar, Stutterwarp drives, colonial nations) from the sidebar — same tool, faithfully adapted rules underneath.

A free, accessible, browser-based character creator and editable sheet for Mongoose Traveller 2022 — every roll cited, every choice logged, every character saved locally. Description Traveller Lifepath is a free, browser-based character creator and editable sheet for Mongoose Traveller 2022. It walks players through the full Mongoose 2022 lifepath — basics and species, characteristics, background skills, pre-career education (University, Army Academy, Marine Academy, Navy Academy), career terms with their full survival / event / commission / advancement loop, mustering-out, the post-creation skill package, and a final reviewable character sheet — without ever leaving a single browser tab.                                                              The tool offers three ways to set characteristics. Players who want the classic experience can have the site roll 2D × 6 into a pool and assign each value to whichever stat they like. Players who prefer their own physical dice can enter results manually; the site still tracks every DM, target, success/failure, and aging effect. Players who'd rather skip randomness entirely can use the included point-buy method (42-point budget, 2..12 per stat). PSI is rolled separately when psionics are enabled, and the Psion career unlocks accordingly.  /images/general-media/1778159165_rhvJ8xSn.png The character-creation rules are implemented as a typed effects engine — TypeScript discriminated unions with exhaustive switching — so every rule lives in one place and can be tested in isolation. The project ships with around 360 automated tests covering qualification, commission, advancement, aging crises, mishaps, life events, connections, the skill cap of 3 × (INT + EDU), pre-career education, and the Mongoose 2022 errata clarifications for Vargr and the Vacc Suit skill. A full audit trail of every rolled die, every applied DM, and every player choice is captured to a roll log that updates in real time. The post-creation sheet is a fully editable Mongoose-style character record. Skills, careers, equipment, weapons, armour, augments, connections, benefits, and free-form notes can all be edited inline; values save automatically to localStorage with cross-tab synchronisation, and the sheet is print-friendly (one panel per printed page, ink-friendly styling). Every character in the local library can be exported and re-imported as JSON for backup or for handing off between players.                                                      Two visual themes are included: a light "Little Black Books" look in the spirit of Classic Traveller, and a dark "Imperial" theme — plus a System mode that follows the operating system's light/dark preference and reacts live when it changes. Theme choice is remembered between sessions.                                                                    Accessibility is treated as a first-class concern. The interface meets WCAG 2.1 AA contrast requirements in both themes (verified by an axe-core audit suite that runs as part of the project's tooling), every interactive element has a visible keyboard focus indicator, icon-only buttons carry ARIA labels, and the layout includes a skip-to-content link for screen-reader users.            /images/general-media/1778159170_sbkOfhno.png Other features include undo across the wizard (rewinds to the relevant picker after popping a character snapshot), URL-based debug logging (?debug=1), the Connections rule for shared PC backgrounds, an aging-crisis path with medical-debt accumulation, and an honest "unofficial fan tool" disclaimer in every place it matters.                            The project is open-source under the MIT License, runs entirely client-side with no backend and no account requirement, and uses privacy-friendly analytics (no cookies).

D-Roller is a free online dice roller built around a real rigid-body physics engine rather than a random number generator. Every throw is simulated — sequential impulses at a fixed 360Hz, full collision between dice, friction and restitution — and the result is read off the geometry of whichever face ends up pointing at the ceiling. Nothing is drawn in advance and nothing can produce a number without the dice actually being thrown. It carries the full polyhedral set — D4, D6, D8, D10, D12 and D20 — and up to twenty dice on the table at once in any mix, so an attack and its damage are one throw rather than two. It also reads a roll the way a table does. Two D20 are shown side by side and never added, because two twenties are advantage or disadvantage and no such total exists; a D20 thrown beside damage dice keeps the attack as the headline and the damage underneath; and a D10 that lands on 0 counts as ten, the way the printing on a real one means. Five die finishes, seven table surfaces, impact sound, and a stage the player can relight. No account, no download, no advertising in the roller. It runs in the browser, on a phone as well as a desktop. Links d-roller.com - Official website

Dragonbane is a classic fantasy tabletop roleplaying game published by Free League Publishing in 2023. It is a modern English translation and reimagining of Drakar och Demoner, Scandinavia's first and longest-running TTRPG, originally released in 1982. The game carries over four decades of Swedish gaming heritage into a sleek, accessible package designed around the philosophy of "mirth and mayhem": fast-paced adventures with minimal prep, where danger is real, luck matters, and even a humble merchant can become a legend. Unlike many modern fantasy RPGs, Dragonbane deliberately avoids the power-escalation treadmill of level-based systems. Characters are capable but mortal from session one, and the game works equally well for a single one-shot evening or a sprawling long-term campaign. It was a strong contender for TTRPG of the year on release, praised widely as one of the most accessible entry points into tabletop fantasy roleplaying. Description In Dragonbane, players take on the role of adventurers in the Misty Vale, a hidden mountain valley, ancient and full of ruins from fallen kingdoms, only recently cleared of orc and goblin occupation. The world is shaped by the eternal cosmic struggle between two great powers: the Dragons and the Demons, rival godlike forces whose conflict bleeds into mortal life. Players choose from six playable Kins: Humans, Dwarves, Elves, Halflings, the duck-like Mallards, and the feral Wolfkin and one of ten Professions (Fighter, Mage, Hunter, Thief, Artisan, Merchant, Mariner, Scholar, and others), each providing a distinct set of skills and heroic abilities. One player takes the role of the Game Master (GM), who builds the world, voices NPCs, and runs the dangers the adventurers face. The tone balances genuine peril and dark fantasy with moments of levity and absurdity.
