Created during the Great Harmonizing crisis when ten league wardens simultaneously channeled their realm's energy into a shared sigil, fusing opposing magics into a permanent stabilizer that vibrates at the Fracture's fundamental frequency.

Emits a subsonic hum detectable across realms; surface glyphs dynamically shift between league-specific motifs; generates visible standing-wave patterns when near rift instability; glows with increasing intensity near dimensional stress points.

Prevents catastrophic realm collisions by reinforcing weakening dimensional boundaries, allowing safe cross-league travel and competition during major events.
