The Covenant Arc manifested during the first recorded moment when wielders from opposing realms chose cooperation over conquest, their combined will crystallizing into a living bridge of intertwined magical energies. This spontaneous creation became the sacred witness to all subsequent inter-realm agreements, growing stronger with each act of unity across the fractured domains.

The Arc shifts its visual appearance to reflect the magical signatures of realms currently in harmony, pulsing with resonant frequencies that strengthen when cooperative energies align and dim during conflicts. Ancient covenant text continuously evolves across its surface, inscribing new agreements and reinforcing existing bonds between leagues. During diplomatic convergences, it generates protective barriers that shield negotiating wielders from chaotic Fracture emissions.

It serves as the living archive and enforcer of all sacred agreements between fractured realms, manifesting to witness crucial diplomatic moments and ensuring that cooperative bonds remain unbroken even during the most volatile magical convergences.
