Poderia ser As Lâminas do Imperador ?
- The main protagonists were a set of 3 siblings, one girl and two boys. I feel like they were triplets as well, but I'm only about 85% sure. They were also important, but I can't remember if it was because of some kind of prophecy or if they were royalty.
- The word "bent" was used as a synonym for "homosexual".
Não tenho certeza sobre isso.
- One of the brothers was not completely allied with the other two siblings and was morally dubious at times.
No terceiro livro, Valyn não está ajudando os outros dois, e eles não compartilham a mesma opinião sobre violência.
- There was some kind of war being fought as well.
Há uma guerra que os irmãos devem lutar para defender seu país.
- It was a medieval-type fantasy setting.
Isto é definido em tempos de tipo medieval, p. espadas, escudos, bestas, e acho que um pouco de magia.
