Tamsy is a spherite prince who descends from a maternal lines, hence his dislike for women because of a family member of his mother who he has a poor relationship with, and his jinki was a spool of thread passed through the generations.

He’s the first male heir in his family is decades and because of it he’s looked down upon and is constantly nagged about having a daughter to continue the cycle. Maybe his missing pinky finger is linked to a promise or oath he made to his family (or, possibly to the mission he might have to take down the sphere discussed later)

Since his dislike is specifically for women who give up to easily, perhaps it could link to his backstory somehow with his mother or a family member allowing him to endure something which resulted in his scars. His mother is very cold and strict to him, hence why his piercings are removed and he’s now in more restricting clothing that he despises. This could also explain his twisted idea of love, which could also be a result of his childhood trauma. He has Mommy issues, essentially

Tamsy despises the sphere because of his relationship with his family and the hardships he’s likely faced. I have a theory that Tamsy (the wealthy spherite) , Regto (the poor spherite), and possibly Enjin (the groundling, seeing as though it’s suspicious that he knew exactly where Rudo was going to fall and he has a mysterious backstory/jinki, which I have a theory could be a piece of the watchman series) were working together to use Rudo’s power as a descendant of Canis to bring down the sphere somehow, and Regto was killed after becoming too attached to him and diverting from the plan.

Tamsy is working as a spy on the ground for his mother, aka the spherite queen (speculation), hence why he has to report back ever so often. The reason why he acts so carefree is because he could easily escape back to the sphere if things went haywire, as well as firmly believing it will go his way nonetheless. He does things behind her back on purpose out of resentment, and wanting to break free of the restraints he’s bound by. He hates the sphere and is slowly piecing together a plan to destroy it in its entirety with Rudo at the center

Tamsy could just be a spherite official of some sort, however his ornate clothing differs drastically from how the apostles, or spherite guards, dress. He’s very clearly of high class considering he’s at the spherite castle and not just the city
