Finally, A theory for you! This is a theory for book nine, Talons of Power! I give myself 47.1% credit for this theory because I published the part that someone commented on. The remaining 56.9% goes to  Alligatorthemudwing for coming up with this! 

     The Book:     

     The Theory:     As some of you probably noticed, Turtle is not wearing his bracelet. Alligatorthemudwing thought that "maybe he enchanted his bracelet to put Darkstalker back to sleep, which would explain why he doesn't have it on." Since "they can't kill Darkstalker and he has unlimited animus magic, the best way to defeat him might be to put him back to sleep." However, I'm not sure if this is the official cover. This "would explain the incorrectly colored glow-stripes." If this is the real cover, I thought that the incorrectly colored spots might be the cause of the sun's reflection. Maybe the spots are blue when normal and look green when glowing. The cover of book six also shows Turtle with blue glow spots.

Also, who is the dragon in the top corner? I was thinking either Anemone, Tsunami, or Moon, because reasons. Furthermore, why does Turtle have a "what the heck" expression on his face? Did someone cook his fish? What do you think he is looking at?

     Words from DuffelSnuff: Again, shoutout goes to Alligatorthemudwing for coming up with 80% of the this theory. Thanks! ^w^
