The run begins before the first card

Choose five heroes. Build one deck.

Who you recruit and who you send into the dark determine your cards, roles and combinations. Change the party, and you change the run.

See the party in motion

Watch a run take shape.

Recruit heroes, combine their cards and take the resulting party into combat.

What you actually do

Build, fight, recover, repeat.

Every system points back to the roster: the cards in your hand, the shape of the frontline and even the choices available on the road.

Recruit the unexpected

Build a roster, not a fixed party.

Nagas, werewolves, ghouls, war bears and winged battle bards would be enemies anywhere else. Here, they are your roster. Choose up to five for an expedition—and adapt when the hero you wanted is recruited first.

One party. One deck.

Combine every hero’s cards.

Every recruit brings signature cards. Send five heroes into the dark and their abilities become a single deck, creating combinations that belong to that party—and that run alone.

Strength is offense and armor

Strike now—or survive what comes next.

Strength powers melee attacks, absorbs incoming damage and decides who holds the frontline when the formation shifts. Spend it for a brutal turn, or preserve it to keep the party standing.

The city remembers

Develop the whole team between expeditions.

Return to a rain-soaked city to recruit, heal, train and promote your heroes. Recovery takes time, veterans may be unavailable, and the same perfect five cannot carry every expedition.

The party changes the road

Your companions have opinions.

When the party encounters a cracked bell in the middle of a swamp, a dwarf may remove its clapper. A sorceress may ring it gently. Walter may simply headbutt it. Bring different heroes and the world offers different answers—and different trouble.

Three ways into the dark

Solo, competitive and cooperative play.

01

Solo

Outthink the expedition

Build a party that can survive the road, its battles and the choices between them.

02

PvP

Draft against a rival

Compete for recruits, deny key synergies and rebuild your plan when the roster changes.

03

Co-op

Share the consequences

Coordinate heroes and cards with another player as one decision reshapes the whole party.

The tavern is open
