The magical dampener is called "Nexarion's Seal." It's an ancient relic created by the powerful dragon sorcerer, Nexarion. This seal is a unique, magical construct that can absorb and nullify magical energies within a specific area - in this case, my stomach.
Nexarion's Seal appears as a intricate, glowing tattoo on the inner lining of my stomach. The tattoo shimmers with a soft, blue-green light and pulses with a gentle, magical energy. When magic is used within my stomach, the seal activates, absorbing and neutralizing the magical energies, rendering them ineffective.
Nexarion's Seal is an extremely rare and powerful artifact, passed down through generations of powerful dragons. Its existence is shrouded in mystery, and only a select few know of its true nature and capabilities.
