The Sigil Terminus manifested at the moment of the Arcane Fracture as a prophetic echo of the event's eventual resolution, born from the collective unconscious desire of all magical forces to reunify. Ancient wielders recognized it as the harbinger of either ultimate magical synthesis or catastrophic collapse, depending on how the scattered sigil energies choose to reconverge.

This enigmatic artifact constantly shifts between the visual representations of all ten league sigils, never settling on a single form for more than moments at a time. It pulses with gravitational energy that subtly draws other sigils and magical artifacts toward it, creating an ever-intensifying field of convergent power. The Terminus exhibits an almost sentient awareness, responding to cross-league events by accelerating its transformations and increasing its gravitational influence on nearby magical energies.

The Sigil Terminus serves as both prophecy and catalyst, actively accelerating the timeline toward ultimate magical convergence across all fractured realms. Its presence forces wielders and factions to confront the inevitable question of whether the reconvergence will restore primordial magical harmony or create an unprecedented catastrophe that reshapes reality itself.
