The cast

Seven heroes. One sealing line.

Sealbound wears cosmic horror on the outside — and a cast of gleeful misfits on the inside. Each hero bends the card game's rules a different way, and the contrast between the dread and the heroes is the whole point. Pair any two and build a deck around them.

Carter

A single spotlight finds her on a stage at the edge of the world.

She is a pop idol — and her song charms orcs, tentacles, even the spawn of Cthulhu into the front row.

Queen — Blink Assassin · DealerBlink Assassin · Dealer
