Harbinger's Sigil

The membrane between worlds is tearing. Beyond it lies the Elder Void — an infinite cosmic darkness teeming with entities that defy comprehension. You have been chosen. Branded with a Sigil, you alone can perceive the rifts and command the horrors that dwell within them.

Harbinger's Sigil is a collectible card game steeped in cosmic horror. Build decks of eldritch entities, forbidden rites, and ancient relics, then battle across dimensional rifts in fast, strategic matches where every sacrifice could tip the balance between salvation and annihilation.

RUNE-BASED COMBAT
Channel five primal Rune types — Void, Flesh, Mind, Star, and Shadow — to summon creatures and unleash devastating spells. Combine runes to unlock powerful Rites: merge Void and Void for Annihilation, weave Flesh and Star for Apotheosis, or twist Mind and Shadow into a Whisper of Madness. Mastering rune combinations is the key to victory.

THE 3-RIFT BATTLEFIELD
Each match unfolds across three dimensional Rifts — contested tears in reality, each warped by unique cosmic modifiers. Control two of three Rifts by the end of turn six to win. Rifts reveal progressively, forcing you to adapt your strategy as new battlefields tear open. Place Entities for raw power, deploy Relics for persistent advantages, and set Whispers as hidden traps for your opponent.

TRIBUTE SUMMONING
Sacrifice lesser creatures to call forth greater horrors. The tribute system creates agonizing decisions — your small entities serve as both fighters and fuel. Chain tributes to summon Elder-tier monstrosities like Azr'thul, the Unborn, whose arrival obliterates everything in its path. Every sacrifice triggers death abilities, turning loss into power.

FIVE FACTIONS, ENDLESS STRATEGIES
- The Sealed Order: Guardians of humanity who wield Star and Mind runes to protect and control.
- The Unraveled: Agents of chaos channeling Void and Shadow to accelerate reality's collapse.
- The Fleshweavers: Biomancers who reshape life itself through Flesh and Star.
- The Hollow Court: Seekers of forbidden knowledge through Mind and Shadow.
- The Rift Wardens: Keepers of balance between Void and Flesh, sealing and opening as needed.

Face the fanatical Commander Solenne, the nightmarish Frayed One, the grotesque Mother Viscera, the enigmatic Archivist, and ultimately the Harbinger itself. Each chapter features standard battles, elite encounters with modified rules, and climactic boss fights with unique mechanics. Earn new cards and unlock rune paths as you progress.
