The main characters in the 'Ancient Dragon Lord Novel' would most likely start with the ancient dragon lord. He would be at the center of the story's action. Additionally, there could be a young apprentice of a powerful mage who becomes involved with the dragon lord. This apprentice might be on a quest for knowledge or power and cross paths with the dragon. There may also be a noble knight who is sworn to protect the realm from the dragon's supposed tyranny, but as the story unfolds, discovers that the dragon lord has his own motives and is not as evil as first thought.
Since it's about an ancient dragon lord, the dragon lord himself is surely a main character. There might also be a human hero or heroine who either befriends or opposes the dragon lord.
The main characters could include the dragon lord, of course. There may also be antagonists, like an evil sorcerer who wants to steal the dragon lord's power or a rival dragon who challenges the dragon lord's authority. Additionally, there could be characters from other species, like a human princess who forms an alliance with the dragon lord to save their respective kingdoms from a common enemy.
The dragon lord is the central character, of course. But there could be other important ones too. Maybe there's a wizard who helps or hinders his return. And there could be a brave warrior who either teams up with the dragon lord or stands against him. There might also be some characters from the dragon lord's past that are relevant to the story, like an old friend or a former rival.
There could be a young wizard as one of the main characters. He might be on a quest to learn the ancient dragon spells.
I'm not sure specifically as there are many novels that could potentially be about 'ancient true dragon art'. But generally, there could be a young protagonist who is on a journey to discover the true dragon art. There might also be an old master who has some knowledge about it.

Perhaps there is an antagonist in the 'lord of light novel'. This character would oppose the 'lord of light' and his followers.

I don't know as I haven't read the 'lord of war novel'. But I guess there would be the 'lord of war' character who is likely to be the protagonist. There might also be his allies and enemies.
In a 'the dark lord novel', the main characters could be the dark lord, who is the source of the conflict. There might be a young and inexperienced protagonist who discovers the threat of the dark lord and decides to fight against him. There could also be side characters like the dark lord's minions, who add to the complexity of the story. For instance, the minions could have their own motives and loyalties that are not always straightforward. And perhaps there is an old and wise mentor figure who guides the hero in the fight against the dark lord.
It's possible that there is a mysterious figure in the 'lord of goblins novel' who has a connection to the origin of the goblins. This character could be on a quest to either help or destroy the goblin race. And of course, there would likely be some loyal followers of the lord of goblins, who play important roles in the story, like his chief lieutenants or his personal guards.
