Mixed feelings about Throné's story

I finished her story today but ended up confused. SPOILERS ahead.

It started well with the lore about freedom. Chapter 2 was nice. Both chapter 3 were amazing, except the part where keys didn't work. Chapter 4 was unexpected and it ruined the story for me.

Immortal Claude lives in a lost city under the sewers and is actually everyone's father ? The guy fights with a baby in his hand ? Sebastian (Father) lost Marietta to his own father (Claude)? Who was the princess mentionned in the tale ?

Also the circumstances of Marietta killing her first baby are poorly written, especially when she said herself "a thief can never steal a baby" ? As a mother, she probably had doubts about killing her baby.

In my opinion, Therion's story was much better in terms of writing. I would love to hear your thoughts !

TL;DR : Throné's end feels weird imo, wby ?
