Twelve-Winged Dark Seraphim
Now that the Big Dipper's been mentioned again, I feel like now is a good time to make my prediction. I was originally going to comment this on the chapter where Merciful Song is introduced, but forgot. I then decided to wait until the Big Dipper was mentioned again. Anyways, my prediction is what the fifth Starlord will be named. When I was doing research to try and see what these guys are like in mythology, I found that the Starlords' names are very similar to names from the novel Martial World. Ravenous Wolf Star, Titan Gate Star, Cherished Kismet Star, and Martial Song Star are all names in that novel. The only names left with Star in the name are Destroyer of Armies Star and Ardent Virtue Star. As such, I predict the next Starlord's name will be based on one of these two.
