Where the veil between the Material Plane and the Feywild thins, the Fae Rat emerges as a shimmering plague. Unlike their mundane cousins, these vermin possess fur that ripples with the iridescent sheen of a dragonfly’s wing and eyes like polished amethysts. They are the stowaways of the sylvan courts, trailing behind faerie caravans and slipping through moonlit rabbit holes into the cellars of mortals. To spot a Fae Rat is to know that your world has begun to bleed into a mercurial realm where logic is secondary to whim. These creatures do not hunger for grain, but for the intangible treasures of a household. A Fae Rat might pilfer the lilt of a singer’s voice, the luster of a silver heirloom, or the warmth of a hearth-fire, leaving behind only cold ash and silence. They nest in the hollows of ancient briars, weaving their beds from stolen dreams and spider-silk. Travelers should be wary when a town’s children stop laughing or the flowers lose their scent; it is a sure sign that a swarm of these glimmering pests has taken root, signaling that a gateway to the twilight realm stands dangerously ajar.
