Marrow Covenant

When the Salt Lake Accords were first signed, the wizards who drafted the treaty discovered that paper alone could not contain the binding magic required to enforce supernatural consequences. To ensure the Accords would never be broken or forgotten, they extracted the supernatural essence from their own bones and wove it into the treaty's foundation. This essence - the Marrow Covenant - became the living marrow of every subsequent signatory, passed down through every signature like an inheritance written in blood and bone.

The Marrow Covenant manifests as glowing veins visible beneath the skin of signatories during curse manifestations, pulsing with bone-white light that intensifies with each rating drop. It produces a deep, bone-warmth that signatories feel in their chest during moments of supernatural consequence, and it pulses in rhythm with curse manifestations occurring at any league, creating a series-spanning heartbeat that connects all players. Most critically, the Marrow Covenant cannot be removed or severed once the Accords are signed - it is the final, unbreakable layer of binding that persists even when every other artifact fails.

The Marrow Covenant serves as the ultimate binding mechanism of the Salt Lake Accords - the last layer that holds signatories to the treaty even when all other artifacts fade, break, or are destroyed. While the Fading Contract deteriorates and the Curse Ledger records consequences, the Marrow Covenant persists as the irreducible essence of the agreement, ensuring that no signatory can ever truly escape the Accords' reach.
