Vell’s Heart is a legendary, glowing artifact resembling a pulsating heart encased in a crystalline structure. The core emits a vibrant, deep blue luminescence, with veins of lighter blue energy coursing through its surface, giving it an organic yet magical appearance. The outer crystal shell is intricately faceted, reflecting light in a mesmerizing pattern, and features subtle engravings of ancient runes that glow faintly when activated.
