I loved the ending. Having Clare's angelic Teresa defeat Priscilla in a very Teresa style was absolutely perfect, and just what I've wanted all this time. Honestly, Teresa is such a hero that she makes me tear up.
Galatea, Irene, Miria, Helen and Deneve all managing to make it through to the end was also a great feeling. I was disappointed that Tabitha died so fast that we didn't have time to feel sad. I somewhat related to her due to being a Miria fangirl.
I'm glad they didn't go the mainland, it was unnecessary for Clare's story.
