The Wildsea - Starter guide

Game book titled 'The Wildsea' with a fantasy design on the cover.What is The Wildsea?

The Wildsea is a fiction-first narrative tabletop roleplaying game designed by Felix Isaacs and published by Mythworks in 2022. The setting is unlike almost anything else in the hobby: three hundred years ago, an event called the Verdancy swallowed the world's civilisations beneath an ocean of impossibly fast-growing trees. Now, crews of wildsailors navigate this riotous green sea aboard chainsaw-driven ships, cutting through dense treetops in search of trade, salvage, and survival.

Settlements cling to the tallest branches or perch atop spits of land that rise above the canopy, always threatened by the relentless growth below. Fire is taboo - catastrophic in an ocean of wood. The vegetation releases a compound called Crezzerin, which is toxic to living things and can warp those exposed to it over time. None of this is set dressing. These facts shape culture, cuisine, trade, and the way people move through the world. The Wildsea commits fully to its premise, and that commitment is what makes it memorable.

How does the system work?

The Wildsea uses a d6 dice pool system built around three outcomes. When a character attempts something uncertain, you assemble a pool of six-sided dice drawn from your character's Edges (broad areas of capability), Skills (specific trained abilities with one to three dots each), and situational advantages. You roll the pool and read only the single highest die: a 6 is a Triumph, a 4 or 5 is a Conflict (success with a cost or complication), and a 1 to 3 is a Disaster that introduces a narrative setback. The pool caps at six dice, which keeps resolution fast and legible.

Rolling doubles adds a Twist - an unexpected development, usually positive, suggested by the other players and the GM. This is one of several moments where the game deliberately spreads narrative authorship around the table.

Characters are built from a combination of heritage (species), history (background), and a set of modular Aspects that define who they are and what they can do. Aspects include things like trained skills, relationships, carried gear, and even companions or pets - and importantly, Aspects can take damage and be temporarily lost, creating a form of attrition that feels personal rather than just numerical.

The GM in The Wildsea is called the Firefly. The group's ship functions as a collective character, with stations assigned during travel. The journey system structures overland travel through the canopy, with different crew members taking roles like At the Helm or On Watch. Progress and threats are tracked using Tracks - the game's equivalent of clocks from Blades in the Dark - which appear throughout play to mark everything from ship damage to brewing faction conflict.

What do you need to start?

The Core Rules is the only essential book - a dense, full-colour hardback of over three hundred pages covering the complete system, setting, six explorable Reaches (regions of the Wildsea world), and all the tools a Firefly needs to run a campaign. The current PDF version is Yewtide 1.3.

Before buying, a free rules kit is available from Mythworks and the free basic rules can be downloaded from itch.io. These give you enough to run a first session and get a genuine feel for the system. This is a genuinely usable free entry point, not just a teaser.

Who is this game for?

The Wildsea is a strong fit for groups who love strange, original settings and want a game that rewards collaborative worldbuilding. If your table is tired of medieval fantasy defaults and wants something with real texture and its own internal logic, this is worth a serious look.

The fiction-first approach means the game leans on players to narrate meaningfully, not just declare actions. Groups who enjoy building atmosphere and history together will get a lot out of this. Pure tactics players or those who want structured progression systems may find it less satisfying - there is no XP ladder, and advancement is tied to personal narrative goals called Drives.

The game handles exploration, survival, discovery, and ensemble crew stories particularly well. It is less suited to tight dungeon-crawl gameplay or combat-heavy sessions, where the Conflict resolution system can feel somewhat abstract.

How does it compare to other systems?

The Wildsea shares DNA with Blades in the Dark - it uses Tracks in place of Clocks, the crew and ship function as a collective entity, and there is a similar philosophy of narrative momentum over granular simulation. But The Wildsea steps further from the playbook structure that defines most Forged in the Dark games, giving players a broader, more modular character creation palette.

Compared to Dungeons & Dragons 5e, The Wildsea is considerably lighter on combat mechanics and considerably heavier on collaborative fiction and setting ownership. If D&D feels like a ruleset that happens to have a world attached, The Wildsea feels like a world that happens to have a ruleset built to serve it.

Where do you start?

Download the free rules kit first. Run a single session - just an introductory voyage with a loose premise and a crew who have a reason to be together. The Wildsea rewards groups who invest in their ship's identity and history early, so spend some time in character creation talking about where your vessel came from.

For the Firefly, read the Reaches before the rules. Understanding the texture of the world helps you run the system with confidence. The official Discord community is active and welcoming, and a strong base of third-party scenarios and supplements exists via itch.io.

The one-shot scenario One-Armed Scissor serves as an introduction to the game and is worth picking up as a structured first adventure.
