Rated M for language, violent scenes, and some spicy stuff.

So what happens when a half celestial who is learning to control his extraordinary powers meets the rebel princess of mewni who is also learning to control the wand?

This is an "Ode to the Stars" a Season 3 AU of Star vs from after Battle for Mewni onwards. What if Jackie broke up with Marco before the Battle for Mewni?

After a chance encounter that leaves him wanting more out of life, Marco soon gets his wish granted, when a certain blonde princess comes to Earth with her entire kingdom in tote.

This story is ultimately Star vs Marco since I love the theory of them being enemies. Marco has had enough of Stars unintentionally bad treatment of him. He wanna break the blood moon curse and be free, he meets the gods Luna and Solis. They help him by turning him into an undead knight, whatever that means. At the same time, they pull him into their conflict.

Title is a work in progress, rated for reasons, vampire installment
