The Dust of Realms is a mystical, glowing powder contained within a small, ornate vial made of aged bronze with intricate Norse engravings. The dust itself emits a soft, ethereal light, shifting between hues of gold, blue, and purple, symbolizing its connection to different realms. The vial is sealed with a rune-inscribed cork, and the surface features subtle wear and tear, indicating its ancient origins and frequent use.
