Called "High Dragon" in common parlance, the constellation Draconis is always depicted by a dragon in flight. Recently, it has come into question whether this was the case in the ancient Imperium. Most Tevinter dragon imagery was reserved for the Old Gods, so why would they dedicate a constellation to dragons in general when specific dragons were held in such reverence? This speculation is fueled by older drawings showing Draconis as more serpentine in appearance, perhaps depicting a sea creature or an unknown eighth Old God that was stricken from historical record.
