Four worlds,
one engine.
A card duel, a hidden-role mystery, a tabletop campaign and a team exercise. Each is built from the same parts: rules with sources, an engine that checks every move and a log that explains it. Pocket Tactics and The Last Supply Route are playable right here.
Two-player card duelGame creators
Pocket Tactics
Three lanes, two Keeps, twelve cards each. Small enough to learn in a minute, interesting enough to break.
- Rule
§4.1 When Spark Imp enters play, deal 2 damage to an enemy unit in an adjacent lane.
- CheckRejected§4.1
Shieldbearer is in the same lane as the Imp. Adjacent means the lane next door.
- Event
damage · spark_imp → lane_runner · 2 · destroyed · §4.1
Hidden-role mysteryLive experiences
The Ninth Lantern
A museum after closing, eight guests, one thief. Phones are the hands; the host runs the night from a single screen.
Guests vote · 6 of 8 in
- Dana 3
- Marat 2
- Ivo 1
- Rule
§2.4 The Keeper may light one lantern each night. A lit lantern shows whether a room was visited, never by whom.
- CheckRejected§2.4
The Keeper already lit a lantern tonight.
- Event
reveal · lantern · archive: visited · seen by keeper only
How it playsEach guest’s phone shows only what their role may see. The engine runs the night in phases (light, move, vote, reveal) and the host steers from one screen.
Tabletop campaignWorlds & campaigns
Hollowmere
A three-session fen campaign. Dice stay on the table; MEKYRA keeps the Canon Ledger so nobody has to remember who drowned.
- C-12
The fen lights follow whoever carries salt.

S2 · 0:58 - C-14a

§1.2 A fact becomes canon when the game master confirms it at the table. Canon can be amended, never silently changed.
- CheckRejected§1.2
“The ferryman is alive” contradicts canon C-14, confirmed in session 2. Amend C-14 or keep it.
- Event
canon · C-21 added · source: session 3, 00:41 · confirmed by GM
