But it's only implied that the Night Furies were hunted to near extinction. There's at least two instances where separate Light Furies are seen that aren't Toothless' mate while we get our first few of the Hidden World and Toothless' "coronation", including an adult with an adolescent nearby in the same scene where Drago's Bewilderbeast shows up. (Obviously a recycled scene that was meant to be near the end after Drago's defeat, and implying the Bewilderbeast was meant to betray him.)

What this means is that Light Furies are at least still reproducing where Toothless is the last of the Night Furies. This brings me to the question of why the Light Fury was considering him as a mate in the first place beyond the dragons apparent cooperation and sentience despite how distantly related the different families are from each other. In nature, competition for resources and courtship behaviors generally keep separate species from reproducing. My only theory is because Toothless didn't know how to court, he simply copied the Light Fury's courtship dance whereas there may be one that Night Furies had before becoming functionally extinct.
