The native territory of the Longhorn has become home to the world's largest and most important dragon reservation. In recent years, the Longhorn has undergone an intensive breeding programme after its numbers plummeted due to the demand for its horn.
The Romanian Longhorn has dark green scales, and two long, glittering golden horns. The Longhorn prefers to gore its prey with its horns before roasting it. The horns of the Longhorn, when powdered, are highly prized as a potion ingredient, and is a Class B Tradeable Material. The Longhorn is seen as being very bulky and large despite being a fairly medium sized species of dragon they appear to have larger muscles. It is also the only dragon that has horns that go straight out like a bull. These long horns and the small one just above its nose in the official artwork make somewhat resemble the triceratops, a dinosaur known and named for its three horns.
