This breed of dragon results from eggs or hatchlings that have been neglected. They are usually rebellious, not obeying their masters, sometimes even attacking them. However, their neglect as a hatchling leaves them crippled, and they are weak compared to other breeds, causing them to stay with their masters for protection.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Laughing Cow of Thaleron is one of the most peculiar dragons in the House of Thaleron. She was born a white dragon: child of a prize dragon, Laughter Thaleron, and a white dragon, Hypersomniac. The first sounds she remembers are the exclamations of disappointment by members of the house, who hoped she would resemble her mother. Her mother, Laughter, was not disappointed by her daughter's breed, but was too easily distracted by funny moments and naps with Hypersomniac to remember to hatch her egg. By the time Laughter realized her forgetfulness, Lady Dodger had already turned the little white dragon into one of her own kind. The little Neglected's first word was "Moo," which is why she was named Laughing Cow. Laughing Cow believes herself to be an actual cow, refusing to admit that she was born of two dragons at all. Although not welcomed by the terrified grazing cows, Laughing Cow refuses to give up the idea that she is, in fact, just a particularly green cow.
