高まった超自然的な知覚を与える神秘的な発光シンボル

A mystical, ethereal symbol, only attainable by select alphas - human or any species - imbues its wielder with unparalleled tracking prowess. This enigmatic mark grants two extraordinary abilities. First, with one radiant, glowing eye aglow, the user's auditory senses are heightened, allowing them to discern even the faintest whispers from miles away, piercing through the veil of distance with unerring clarity. Second, when both eyes blaze with an otherworldly light, the user's perception expands, granting them the uncanny ability to sense motion through solid objects and the earth itself, their hand or foot becoming a sensitive antenna, detecting the subtlest vibrations from every direction, an omnidirectional awareness that transcends the limits of mortal perception.
