Echoes of the Sunken Citadel

With swirled deep-sea blues, smoky dark clouds, metallic teal ink, and smooth pale inclusions nestled within each die, these look like remnants of lost oceanic relics, ivory bones, or glowing sea glass churning in a storm.

Echoes of the Sunken Citadel

Off the treacherous coast of the Bleak Reaches, where frigid waters plunge into lightless oceanic trenches, sits the drowned ruin of Aethelgard—a once-mighty floating sanctuary built by moon elves and mariners. Centuries ago, a cataclysmic tempest shattered the sanctuary’s leviathan-bound wards, dragging its spires into the abyss.

Legend speaks of the Eldritch Tide, a localized supernatural surge that swept through the sinking ruins. It suspended the shattered ivory columns, trapped air bubbles, and swirling dark waters into moments of frozen, eternal stasis. Artisans who later braved the abyssal depths harvested these crystallized fragments of storm-churned water and ancient elf-bone, carving them into seven sacred polyhedrals to honor the lost city.

The metallic teal numbers were etched with glowing algae-infused inks used by deep-sea cartographers, ensuring the markings could be read even in the pitch-black reaches of the underworld.

Campaign Mechanics & Flavor

• Ebb and Flow (Nat 20): A critical roll causes the blue mist inside the die to catch the light like churning waves. The player gains a temporary surge of momentum, granting them water breathing for 10 minutes or advantage on their next Athletics/Acrobatics check.
• Grip of the Deep (Nat 1): A critical failure manifests a phantom chill. The player experiences a momentary sensation of crushing pressure, reducing their movement speed by 10 feet until the end of their next turn.
• Whispers of Aethelgard: When held near the ear in absolute silence, the dice faint faintly resonance with the muffled roar of distant breaking waves and forgotten elven sea-hymns.
