Lately, I've had a lot more time to continue writing my story, and I've been able to notice a lot of problems with it such as a passive protagonist, a heavily sagging middle, and a plotline that doesn't make any sense. I've been able to solve some of these issues or I'm in the middle of trying to fix them. However, one problem that I've been having a difficult time with is making the second main character stand out. To give some context, this character, Corvus, was basically cursed to be an immortal servant as he committed a certain crime that even the gods found offensive. Due to this, he lives out his days serving under the rule of a goddess as repentance for he's done. One of the tasks he was given was to watch over a boy, the protagonist, who has certain abilities that the goddess has been looking for. There's a whole plan that she has that involves Sulja, with the ending being that he dies. After watching the protagonist grow up and even interacting with him, Corvus becomes attached and doesn't want him to die. So, he and Sulja come with an alternative plan that has Sulja taking his life into his own hands. Essentially, they go on a journey to save the Sulja's life and, hopefully, the world. With that being said, I want to make Corvus stand out as his own person outside of just being the main protagonist's protector and guide. So, any suggestions? Sorry if the description was pretty vague, but if you need anymore context, feel free to ask.
