Measuring 3 to 5 meters in length, it hunts in coordinated packs using ambush tactics and terrain manipulation. Domesticated by dwarves and humans, it serves as a loyal companion in war and wilderness alike, exhibiting primate-level intelligence and deep social memory."

   "full": "Glasslings are delicate, translucent shapeshifters that rely on refraction and illusion rather than physical transformation. Their bodies bend light to mimic individuals, animals, or environments. Found in Irudy’s crystal caverns and Siniath’s coastal grottoes, they are not predators, but enigmatic reflections of the world around them. Their presence unsettles or inspires depending on one’s beliefs, appearing as statues, mirages, or mournful shades by the sea."
