Night Fury

A Night Fury (Noctodracus Berkilandus) is an extinct animal part of an extinct group of reptiles called dragons. The night fury was about the size of a rhinoceros in weight due to having hollow bones rather than solid bones despite being almost elephant-sized. an excellent flier and was one of the fastest fliers of the dragon world, possibly flying about as fast as 250 miles per hour, thanks to its streamlined body. As their name suggests, they were nocturnal and were black in color, implying that they used the dark of the night to blend in while hunting prey items.

Extinction
Just like the Mountain Dragon, Night Furies were hunted to extinction by knights and vikings after night furies hunted their livestocks.

However,just like the Marine Dragon, Forest Dragon, and Mountain Dragon, there are sightings of Night Furies being around alive and well, although they remain as cryptids.
