Durhilian

The Durhilians of Durhiel are a mortal race descending from dragons. The Durhilians of Xanwinter (known as Xan'taur in durhiel) originally lived on Durhiel but escaped the destruction of their homeland to Thalas during the First Flame Invasion.

Origins
Legends say Durhilians were originally dragons who took residence on the continent of Durhiel. These dragons lived in the caverns of Mount Terreciar, hiding from the scorching sun. With enough time, the dragons adapted to their cave environment losing their wings and with that, their ability to fly. Their physical form grew much smaller to fit their new living space and they started prefer walking on two legs. Living in their mountain, this group of dragons gave little care to their sacred duties given to them by the Titans and thus their connection to the gods decreased eventually causing them to lose all their magical dragon abilities as well as their long lifespans.
