The Princess in the Castle

From publisher blurb:

A princesa está presa no quarto mais alto da torre mais alta aguardando o seu resgate, seria você esse herói?

Due to a horrible curse that besets his daughter, the king has decided to keep her isolated in a castle far from the city for her protection. The curse was placed at the behest of a conspirator against the crown, no one knows its real effect, only that it affects the princess from dawn to dusk. Due to the castle being isolated, the king ordered trusted guards to take care of the place, but it didn't take long for opportunistic creatures to eliminate this protection and make the place their abode. Knowing this terrible news, the king is secretly summoning adventurers to search for his daughter and bring her back.
