The Synthesis Rune manifests as a living runic inscription that continuously rewrites itself, adapting its symbols to harmonize whatever conflicting magical energies surround it. Its surface shifts between the color schemes of all ten leagues in flowing transitions, while generating stabilizing harmonic frequencies that calm volatile magical interactions. The rune's patterns pulse with synchronized energy that can temporarily override the natural antagonisms between opposing magical schools.

The Synthesis Rune serves as the inscriptive foundation for all magical unity within the Fracture, automatically generating the runic formulas needed to bridge conflicting realm energies during unprecedented cross-league convergences.
