Dice became a real part of a world. Roll tables with weights or classic d100 ranges, rich text outcomes, and a library shared across the whole world. Roll buttons sit on Free boards and tumble 3D dice with a per die breakdown. Inline dice chips live in any page and work in the read-only share view, so players can roll while your prep stays put. Saving also got faster: the app now sends only what changed.

Overview

Trails Weaver is a visual worldbuilding app for game masters, worldbuilders and writers. Every character, location, faction and item is a page with rich text, images, custom properties and a relations table, and any page can also be dropped onto a board. There are four board types: - an infinite free board where element cards nest inside other element cards. - map boards with pins, regions and roads that reveal more detail as you zoom in. - hierarchy boards for family trees and chains of command. - relationship graph that assembles itself from the relations recorded on each page Anything marked secret stays hidden when a world is shared through a read-only public link. The free plan covers one world, unlimited free-boards and up to 25 world elements. Pro removes every limit.

Key features

Cards inside cards

Element cards nest inside other element cards on an infinite board. A city holds its districts, a district holds the people who run it.

Notes that think they're pages

Sticky notes on a board carry headings, tables and to-do lists, and connect to each other when the plot does.

Share without spoilers

Send a world through a read-only link. Anything marked secret stays hidden from everyone you share it with.

A graph that draws itself

Record a relation on a page and it shows up in the relationship graph. Filter to one house or faction and the rest falls away.

More than family trees

Map bloodlines, noble houses, guild ranks, pantheons and chains of command. Every tree lays itself out as you add to it.

Maps that open as you zoom

Upload a map, draw roads and regions, drop pins. A country reveals its cities, a city reveals its districts.

Talislanta

High-Fantasy
Rules-medium
Heroic
Talislanta is a fantasy tabletop roleplaying game created by Stephan Michael Sechi, first published by Bard Games in 1987. It draws its inspiration from Jack Vance's Dying Earth novels and the travelogue spirit of the Arabian Nights rather than from Tolkien. It built its identity around a single blunt promise printed right on the box: "no elves". No dwarves, no halflings, no standard-issue fantasy races at all - just dozens of original cultures found nowhere else in the genre.  The game has passed through five editions and nearly as many publishers, including a stint at Wizards of the Coast in the early '90s, and creator Stephan Michael Sechi now makes the entire back catalogue - every edition, every supplement - available for free through the official Talislanta Library. Description Playing Talislanta starts with a choice. Instead of creating a character from separate race, class, and skill lists, players pick one of well over a hundred archetypes. Things like the Cymrilan Rogue Magician, the Jaka Beastmaster, or the Mandalan Mystic Warrior - each one a fully realised character tied to a specific culture. Complete with attributes, skills, gear, and a place in the world already worked out. A little light customisation (a point moved here, a skill added there) and the character is ready to play.  What makes the game distinct isn't its mechanics, which are deliberately light, but the scale of its setting: the continent of Talislanta is home to more than a hundred distinct peoples, and the rulebooks spend far more pages on culture, custom, and worldview than on combat math. It rewards players who want to explore a genuinely alien fantasy world over chasing mechanical optimisation. System Overview & Key Features Archetype-Based Character Creation Character creation isn't a build process, it's a selection process. Every archetype in the book arrives fully statted, dressed, and equipped, tied to a named culture and a defined role in Talislantan society. Archetypes are deliberately unbalanced against one another, since staying true to the setting mattered more to Sechi than parity between character options. The Unified Action Table Skill checks, combat rolls, and magic all resolve on a single d20 chart. Attacking works exactly like any other skill roll: add a skill rating, compare to a target number. There's no separate combat subsystem to memorise, which keeps the rules themselves down to a few dozen pages even in the densest editions. Modes and Orders Magic runs on two interlocking pieces: Modes (twelve broad effect categories like Attack, Heal, or Illusion) and Orders (culturally rooted schools of magic, from Cartomancy to Elemental Magic). A magician's Order shapes how a Mode behaves and looks when cast, so the same underlying effect plays out completely differently in different hands - which lets a short list of Modes support a near-endless variety of actual spells. A World Built Without Tolkien Every culture in Talislanta was designed to avoid genre default: no elves, no generic barbarians, no standard dragons. In their place are peoples like the Thralls (identical clone-warriors distinguishable only by tattoo), the sky-sailing Phantasians, and the shapeshifting Sindarans. The setting material - not the rules - is where most of the page count and most of the game's reputation live.

Delta Green (2016)

Delta Green (2016)

TTRPG
English
Horror
Delta Green is a standalone tabletop roleplaying game of modern conspiracy and cosmic horror. Originally a supplement for Call of Cthulhu, the current standalone edition was published by Arc Dream Publishing in 2016. Players take on the roles of federal agents or contractors working for a secret, illegal organization dedicated to containing supernatural threats and covering up the existence of the Cthulhu Mythos to protect the United States. The system it directly evolved from is Call of Cthulhu Description In Delta Green, the horror is not just about monsters; it is about the toll that a life of secrecy and violence takes on the human soul. Agents juggle their high stakes investigations with their crumbling personal lives. They must navigate a world of bureaucratic red tape, government conspiracies, and sanity shattering entities while ensuring that no one, not even their own families, ever finds out the truth. The game is famous for its bleak tone and focus on the cost of the "Great Work." System Overview & Key Features d100 Percentile System The game uses a familiar percentile dice engine. Skills are rated from 01 to 99. To succeed, you must roll equal to or under your skill rating. If the tens and ones digits match (a double) and the roll is a success, it is a critical success; if it is a failure, it is a critical failure. Bonds and Domestic Ruin Agents have Bonds representing their relationships with loved ones or colleagues. When an agent suffers Sanity loss, they can choose to project that trauma onto a Bond to reduce the loss. This mechanically represents the agent coming home and taking their trauma out on their family, slowly destroying their personal life to stay functional in the field. Sanity and Adaptation The game tracks three types of Sanity loss: Violence, Helplessness, and the Unnatural. If an agent experiences enough Violence or Helplessness without breaking, they can become "adapted," making them more resilient to those triggers but less capable of maintaining human empathy and Bonds. Lethality Rating Instead of rolling many dice for heavy weapons like assault rifles or explosives, Delta Green uses a Lethality percentage. If the player rolls under this rating, the target is instantly killed. If they roll over it, the weapon deals a fixed, significant amount of damage instead. The Home Phase Between missions (Operas), players play through a "Home" scene. They must choose how to spend their limited time: fulfilling responsibilities to maintain Bonds, seeking therapy to recover Sanity, or practicing skills. Choosing one often means neglecting the others, leading to a downward spiral of isolation. Special Training and Agencies Character creation is deeply rooted in real world professions. Whether you are a CIA Case Officer, an FBI Special Agent, or a CDC Epidemiologist, your profession dictates your starting skills and the federal resources you can leverage during an investigation.
