Forged during the first catastrophic breach of the Arcane Fracture, the Sigil Covenant emerged as a living contract between the earliest Wardens and the Veil itself. Its intertwined glyphs contain suppressed memories of forgotten stabilization rituals, activated only when reality's threads fray beyond normal repair.

The sigil pulses rhythmically like a heartbeat when near unstable magic, its outer lattice hardening in response to arcane threats. UV-reactive channels along its fracture lines reveal hidden binding oaths when exposed to moonlight. Stored glyph energy can temporarily mend minor reality tears through precise sigil alignment.

Serves as both arcane contract and emergency stabilization tool, automatically reinforcing weakening reality threads near its bearer. Activation forces temporary truth revelations from those touching its surface.
