One Realm is an AI-assisted campaign workspace and virtual tabletop built for groups that want to play tomorrow—not spend the week preparing. It turns adventures, source material, and campaign notes into an organized, playable world, helping GMs complete work that might otherwise take hours or days in a matter of minutes. Characters, locations, encounters, maps, relationships, and story events are automatically organized and connected. From there, the GM can prepare scenes, create artwork, manage characters, and run the game through the integrated virtual tabletop. Because everything shares the same campaign context, preparation flows directly into play without rebuilding the session across multiple tools.

RPG Map is a free, browser-based map viewer built around gradual map reveal — Fog of War. It's not a map-making suite and doesn't try to be one (for creating maps, tools like Dungeondraft or Watabou's generators are a better fit). Instead, it focuses on one thing: taking a finished map and revealing it to your players piece by piece, in person or online. The GM loads a map and shares a link. Players open it on any device — laptop, tablet, or phone — and everything stays in sync in real time: as the GM erases fog, moves tokens, or pans the view, players see it instantly. No installation, no account, no ads, and no fees. Features: Fog of War — reveal the map gradually with a simple brush and eraser Realtime synchronization — players follow the GM's reveals live via a shared link Drag & drop tokens — place and move character and monster tokens on the map Automatic grid detection — the grid aligns to your map without manual setup Built-in library — free maps and tokens to get started right away Mobile ready — works in the browser on phones and tablets, nothing to install Whether you play at a physical table with a shared screen or fully online, RPG Map keeps setup to seconds: open, load, reveal.

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.

Pathfinder is a heroic fantasy roleplaying game system with a high amount of character customization and progression, published by Paizo in 2009. It was developed as a response to Wizards of the Coast transitioning the D&D genre to D&D 4th Edition, which was seen as a strong deviation from the math-heavy norm from 3.5E. Pathfinder was built using the Open Game License (OGL) to revise and expand upon the beloved 3.5 ruleset.  The system it directly evolved from is Dungeons & Dragons 3.5 Edition The second edition of the game was released in 2019 as Pathfinder 2nd Edition Description Pathfinder 1e is well known for its "crunch". It relies heavily on strict rules, mechanical variation and math. The system is perfect for players who prefer heavy character optimization and customization, focus on tactical combat encounters and a strong ruleset for almost any situation. Pathfinder is proud of it's complexity and very much focuses on it. Boasting a massive library of  spells, classes, and feats, allows the players to build very mechanically different and unique characters. It is also renowned for its "Adventure Paths": epic, six-part published campaigns that take characters from level 1 to roughly level 20. System Overview & Key Features The d20 System & Action Economy Like 3.5E, the core engine runs on a d20 roll plus modifiers. On every turn the characters have a set structure to perform their actions. Mechanically separated into Standard, Move and Swift actions. Archetypes & Deep Customization Instead of relying on complicated "Prestige Classes," Pathfinder 1e popularized "Archetypes." These allow players to swap out base class features for heavily themed alternatives right from level 1. This enables the players an extensive levels of customization when combining with the thousands of available feats to further personalise their unique character concept. Base Attack Bonus (BAB) Martial prowess is measured by a Base Attack Bonus. As this number grows, martial classes can eventually achieve "iterative attacks," allowing them to attack with their weapons multiple times per their turns, although penalties apply for repeated attempts. Combat Maneuver Mechanics (CMB/CMD) The system introduced two systems to simplify actions like tripping, grappling or disarming your opponents: Combat Maneuver Bonus and Combat Maneuver Defense. This created a single, reliable formula to use when performing maneuvers against an enemy. Skill Ranks Instead of a single "Proficiency Bonus" like in modern games, players are given a pool of Skill Points at every level (determined by their class and Intelligence score) to manually distribute across a massive list of skills, allowing for highly granular non-combat abilities. Lethality and "Crunch" As characters level up, the numbers grow exponentially. This means, that by reaching higher levels of encounters, characters and their opponents are dealing huge amounts of damage, alongside with various magical buffs and spells that could instantly kill a character. Planning and tracking situational modifiers and buffs becomes vital for survival.

SHRINES – A Dark Pilgrimage RPG is a classless dark fantasy tabletop roleplaying game about dangerous pilgrimages through wounded worlds. It combines tactical D6-pool combat, exploration, escalating threats and character growth through Domains with a strong focus on consequence, discovery and gaining knowledge. Description SHRINES – A Dark Pilgrimage RPG is a dark fantasy tabletop roleplaying game in which the players take the roles of the Marked, pilgrims bound to mysterious Shrines and sent into regions scarred by ancient wounds, broken beliefs and hostile forces. The game combines tactical combat with exploration and narrative decision-making while keeping bookkeeping deliberately light. Its core system uses pools of six-sided dice, with characters defined without traditional classes. Instead, they develop through their qualities, talents, maneuvers, equipment and Domains - powerful influences that shape abilities, vulnerabilities and interactions with the world. Shrines form the anchors of every pilgrimage. They provide safety, progression and a place to return to, because death is not the end. When a pilgrimage fails, the Marked may return to their bound Shrine, but failure still carries consequences. Lost Essence, Burden and an increasingly dangerous world ensure that reformation never makes defeat meaningless. Exploration is built around regions, locations and Instances rather than long quest lists. Players uncover Lore, discover competing factions and decide how deeply they are willing to involve themselves in conflicts that rarely offer a simple distinction between good and evil. At the same time, Regional Escalation causes the world to react to the actions and failures of the Marked, making prolonged expeditions increasingly dangerous. SHRINES is designed around the idea of fair cruelty: the world is harsh, combat can be deadly and mistakes matter, but danger is meant to be readable and consequences understandable rather than arbitrary. The game can be played with a group or as a solo pilgrimage. Its free introductory series, SHRINES: INITIATION, guides players step by step through the core ideas of the system across four connected episodes, gradually introducing exploration, combat, navigation, escalation and the consequences of failure. It leads directly into FIRST FRAGMENT, the upcoming Quickstart release, which expands SHRINES into a broader playable region with additional rules, characters, locations, monsters and a complete pilgrimage to undertake.
