I don't know for sure as I haven't read it. But I would expect the healer to be one of the main characters. There might also be a mentor figure who teaches the healer or helps them improve their skills.
The healer is surely a main character. There could be a sidekick, like a warrior or a mage who accompanies the healer on their adventures. And perhaps there is an antagonist, someone who is causing the problems that the healer has to fix, like a dark wizard who spreads diseases or curses. Maybe there's also a love interest for the healer, which could be another important character in the story.
Without reading the novel, it's hard to say exactly. However, if it follows common tropes, there could be a healer as the protagonist. Then, there might be friends or comrades that the healer meets along the way. These could include other healers with different specialties or characters from different races or backgrounds. There could also be a villain who wants to stop the healer from achieving their goals, whether it's to save a certain person or to spread healing throughout the land.
