Jermlaine in Dungeons & Dragons are tiny, malevolent fey creatures, standing only about 1 to 2 feet tall. They have wrinkled, rat-like faces, leathery gray skin, and sharp, beady eyes. Known for their cunning and cruelty, Jermlaine dwell in dark, subterranean environments like caves and dungeons, where they create elaborate tunnel systems.

These creatures are highly intelligent and adept at setting traps and ambushes, often using their small size to their advantage. They are skilled in stealth and can move silently through their tunnels, making them difficult to detect. Jermlaine are scavengers and thieves, known to harass and steal from larger creatures.

Despite their size, they can be dangerous in large numbers, swarming their enemies with hit-and-run tactics and employing poisoned weapons. Encountering Jermlaine is a test of wits and caution, as their traps and numbers can overwhelm unprepared adventurers.
