The sigil is a small, palm-sized fragment of smooth obsidian that seems almost impossibly dark, absorbing light around its edges. Etched across its surface are intricate arcane runes that glow faintly in shifting colors—sometimes gold, sometimes a deep violet, almost like liquid fire moving beneath the surface. The symbols are unfamiliar to any single scholar but radiate a sense of powerful magic and latent danger. The fragment is irregularly shaped, jagged on one side as if it broke from a larger whole, yet the edges feel unnaturally smooth to the touch. When held, it emits a subtle vibration, like a heartbeat, and the air around it grows slightly warmer, tinged with faint static energy. Light reflecting from it occasionally forms fleeting tiny illusions, like shadowy figures moving just at the periphery of vision, hinting at the sigil’s connection to some unknown, possibly otherworldly force. Despite its beauty, the sigil fragment gives off an uneasy sensation, warning that it is both powerful and dangerous—an artifact that could open gateways or attract enemies if mishandled. See more
