Keystone of First Ghasthund

The Keystone of First Ghasthund is Randidly's sixth and final Fateset piece. Created from the blank Paradox of the Alchemist, it completes his Fateset and develops the dangerous ability to extend an invitation to virtually any individual. (Chapters 2178, 2191)

History

Giving the blank Fatepiece an identity

Mastery of the Codex Hexahedron reveals a black, scoured-clean sixth piece whose name and abilities must be defined irreversibly. Randidly instills it with the legacy of the First Ghasthund and obtains the Keystone as his final Fatepiece. (Chapters 2178, 2191)

Completion before maturity

Even before reaching its maximum level, the Keystone joins the other five Fatepieces in Pantheon's Intervention. It later reaches Level 100, securing its mature place in the set. (Chapters 2211, 2238)

Invitations across impossible boundaries

The mature Keystone can invite an individual into an experience or state prepared by Randidly. It makes memory-born people real, and Randidly later uses it to invite Nyx, a foreign Eternity, into a conversation despite the gulf between their existences. (Chapter 2279)
