The Dragon of the Mountain appears to be the only one of its kind. Its relationship to the dragons of Deltora is unknown, although it shares several traits, including fierce territoriality; it will attack any foreign presence in its airspace, although it is unconcerned with invasions on the ground. It seems similar in appearance to Deltoran dragons. However, it has never been known to speak human language, and has not displayed the level of intelligence characteristic of Deltoran dragons. It is very rarely seen away from the Mountain.
