Candela Obscura - Starter guide

What is Candela Obscura?

Candela Obscura is an investigative horror RPG published by Darrington Press, the tabletop arm of Critical Role. You play members of a secret society who hunt down occult threats seeping through a barrier called the Flare, working assignments handed down by mysterious superiors known as Lightkeepers. It is Gothic, moody, and built for shorter story arcs rather than years-long campaigns.

The idea began in 2018 with Critical Role co-founder Taliesin Jaffe and writer Chris Lockey, drawing on Jaffe's love of cosmic horror and a Call of Cthulhu scenario that first sparked the concept. Spenser Starke and Rowan Hall developed it into a full game, using the Illuminated Worlds system built by Stras Acimovic and Layla Adelman, a design Starke has credited as pulling heavily from Blades in the Dark and, notably, Vaesen. Candela Obscura first appeared as an actual play series on Critical Role's channels in 2023, with Matthew Mercer running the first arc, before the Core Rulebook released that November as both a standard hardcover and a collector's edition. As an official Darrington Press Guild Store, Netherbook carries the same edition sold at Darrington Press and Critical Role's own shops.

How does the system work?

Illuminated Worlds runs on pools of six-sided dice. Each Action your character can take has a rating from 0 to 3, and when the outcome is uncertain you roll that many dice and take the single best result. A 6 is a full success, a 4 or 5 is a success with a complication, and 1 through 3 is a miss. Roll more than one 6 and you get a critical success. A pool never exceeds six dice, which keeps even a favorite Action from spiraling out of control.

Every character draws on three Drives: Nerve for physical Actions like Move and Strike, Cunning for social Actions like Sway and Read, and Intuition for perceptive Actions like Survey and Sense. Spending a point from the matching Drive adds a die to a roll. Some Actions are gilded, meaning one die in the pool is a different color; choosing that die as your result, even if it is not the highest, refunds a point to the Drive it belongs to. When a roll goes badly, players can also burn a Resistance to reroll, a resource that ties directly back to how much Drive they have banked.

Instead of hit points, characters take Marks across three tracks: Body for physical harm, Brain for mental strain, and Bleed for magickal corruption. A fourth mark on any track knocks a character out of the scene and leaves a Scar, a permanent shift that changes how the character plays going forward. A character can carry up to three Scars; a fourth ends their time in the field, in whatever way the table decides fits the story.

What do you need to start?

The core rulebook is the entire toolkit: complete rules, character creation, sample assignments, and setting information covering the city of Newfaire and the wider Fairelands. Character creation starts with one of five roles, Face, Muscle, Scholar, Slink, or Weird, each offering two specialties that shape a character's Drives and Actions from the outset. Darrington Press also released a free quickstart guide alongside the show's 2023 premiere, worth checking their website for if you want to try a single assignment before committing to the full book.

Who is this game for?

Candela Obscura suits groups who want investigative horror with a strong narrative pulse and sessions that wrap up in a handful of sittings rather than open-ended campaigns. If your table enjoys Gothic mystery, character consequences that actually stick, and a GM whose job includes spending narrative currency rather than just rolling dice, this fits well.

It is a poor match for groups chasing tactical combat or long-term power growth; there is very little of either here. And if you prefer a system where the GM's authority stays mostly narrative rather than mechanical, note that Illuminated Worlds gives the GM real dice-fed tools to complicate scenes, which changes the table dynamic more than some groups expect.

How does it compare to other systems?

Against Dungeons & Dragons 5e, Candela Obscura barely overlaps. There is no combat-as-sport, no long build path, and success or failure is rarely just a number: it is a Mark on your character that may never heal.

The nearer comparison is Call of Cthulhu, the game that indirectly inspired this one. Both send ordinary-feeling people against forces they cannot fully understand. But Call of Cthulhu resolves with a single percentile roll and tracks Sanity as a slow-draining resource, while Candela Obscura's dice pools and Marks and Scars system build consequence more gradually, scene by scene, rather than through one dramatic breaking point. And the Illuminated Worlds system openly borrows structure from Vaesen: both use six-sided dice pools built for atmospheric mystery, though Vaesen keeps its investigators searching the Nordic countryside while Candela Obscura sends its circle into a Gothic city on the edge of another world entirely.

Where do you start?

Read the core rulebook's rules chapter together as a table before character creation; the Drives and Marks and Scars systems land better once everyone understands the shape of a session. Then build your circle and run one of the sample assignments included in the book, which are designed to work as standalone one-shots.

One piece of advice for the Lightkeeper at the table: let the Marks and Scars accumulate. The system only delivers its emotional payoff when consequences are allowed to actually change who a character is.
