However, several characters could be considered faithful servants based on their actions and loyalty:
* Dobby: He's fiercely devoted to Harry and will do anything to protect him, even if it means defying his previous master and breaking house-elf rules.
* Rubeus Hagrid: He's incredibly loyal to Dumbledore and Hogwarts, and his dedication to his job is unquestionable, even when facing accusations and scrutiny.
* Mrs. Figg: While not a staff member, she's a dedicated member of the Order of the Phoenix and proves to be a faithful servant to the cause of fighting Voldemort.
* Elphias Doge: A close friend of Dumbledore and a member of the Order, Doge is a loyal servant to the cause of good and a reliable ally.
* Nymphadora Tonks: Though she's a member of the Order, she shows particular devotion to Dumbledore and the fight against Voldemort.
It's important to remember that "faithful servant" can have different interpretations. Therefore, the best answer depends on the specific context and what qualities you consider most important for a servant.
