Qinterwatcher, a.k.a "Three Moons", is a fanon ship from Wings of Fire's second arc. It's mostly Qibli and Winter with Moon acting as a spectator. The trio came to be after Moon decided to choose neither of the two, and instead chose to be a close friend that's supportive of the relationship that bloomed between the prince and the former Outclaw. Putting it simply, this would've been a nice ship to have in the actual canon. Nothing bizarre here, just three close friends getting along perfectly.
