The world
Sealbound: Cthulhu Rising is set in a 1930s Lovecraftian Earth where the seals between worlds are failing — and a single run decides how long the lights stay on.
Steam, séances, and silver-screen monsters. Across the great cities of a 1930s world, eldritch gates tear open and the things behind them do not care about borders. The tone is scary but fun — cosmic dread played with a pulp-adventure grin.
The world map tracks every gate as it collapses and rages. Each loss pushes the Doom Counter toward ten; every first-time purge drags it back down. Let Doom reach ten and the gates close for good — the timeline resets and a new world begins.
Nyarlathotep, Ithaqua, Hastur and others don't arrive as damage races. Each hides behind an immunity puzzle — read the rule they're protecting, then build the one line of cards that breaks it.
Clear the world gates and the run drives toward a final, three-phase raid beneath the waves. It is the sealing line the whole campaign has been building toward — and the last thing standing between this timeline and the dark.
Gate status, regional threat, boss previews, rewards, and the Doom Counter all read from one command surface. Choose where to strike before the next gate falls.
Every gate is its own tactical board. Roll the dice and route through battles, treasure, shops, rest, events, and elites toward the boss tile and the raid beyond it.
Step through a gate and see how long you last.
