Brightness Dragon Lord

Brightness Dragon Lord (ブライトネス・ドラゴンロード) is a Dragon Lord, one of the most powerful dragons in the New World.

Personality
Due to his habit of experimenting and breeding with other races, he is most feared by fellow Dragon Lords. Said to have the mind of a scholar rather than a warrior, the Brightness Dragon Lord is considered a loner due to his unique hobbies. It was revealed that none of the Brightness Dragon Lord's brethren seems to have a clear understanding of him because of his own way of thinking and why he does things the way he does. According to the author Maruyama, the said Dragon Lord has a perverted mindset to the point that he tends to shout out sexual lines during the act of copulation with a female.

Background
Brightness Dragon Lord was the founder of the Dragon Kingdom. Currently, the Dragon Lord's great-granddaughter rules the Kingdom in his place through inheritance from his previous descendant to where she is now. This Dragon Lord's perverted nature led to fear among his colleagues as well as his eccentricities being part of it. His residence was said to be held at the top of a mountain located around the center of the continent. Rigrit noted that he has been mingling around with humans while making babies.

While so, he seems to teach some of his offspring about Wild Magic as they inherited the capability to use Wild Magic, educating them on how to use this ancient magic system. For example, he happens to play a scholarly role in his great-grandchild's upbringing who at some point in time, became the queen of her own nation currently. He taught his offspring a variety of details about the fundamentals of using Wild Magic and how his other True Dragon Lord brethren can access it and the most powerful spells they can cast.

The Invaders of the Large Tomb Arc
Rigrit Bers Caurau asked Platinum Dragon Lord if they should reach out for help from the other Dragon Lords to combat the new threat that had appeared in the New World. Particularly, she mentions the Brightness Dragon Lord and noted that he had children with humanity in the past. With his friend's suggestion in mind, Platinum Dragon Lord considers swaying Brightness Dragon Lord to their side. However, he figures that there will be a higher chance of obtaining aid from the Sea City rather than seek his colleague out.

The Magic Caster of Destroy Arc
Fluder Paradyne mentions that Brightness Dragon Lord's blood flows within Draudillon Oriculus's veins, allowing her the ability to use Wild Magic. Realizing that only descendants like Draudillon who shared the same bloodline as Brightness Dragon Lord can use Wild Magic, Fluder encourages Jircniv to marry her, but the latter was against the idea of doing so since she isn't his ideal type.

Abilities and Powers
Given the fact that Brightness Dragon Lord is the ancestor of Draudillon Oriculus, who is capable of casting Wild Magic, it can be concluded that he too should be able to use it. Since he is a true-blood dragon among Dragon Lords, the cost of using Wild Magic is by far not as severe as it would be for his great-granddaughter. He is not the least bit interested in fighting, seeing the engagement of combat as nothing more than an annoyance to him. According to Maruyama, he is intelligent like that of a scholar. This may have been partly the reason why he did not bother to confront or challenge the Eight Greed Kings' rule five centuries ago with his fellow Dragon Lords. The tier spell [Time Stop] is ineffective against Brightness Dragon Lord.

Wild Magic Spells:

 * World-Warping Wall: It creates a teleport-blocking barrier, trapping the foe from using teleportation magic within the user's surroundings. In a way, the World-Warping Barrier simply interferes with teleportation through it. So, teleportation was possible as long as the start and endpoints were both inside the barrier. An enemy could simply teleport to the edge of the barrier and then walk right through the barrier itself.

Draudillon Oriculus
While she is his great-granddaughter, they don't appear to be in contact as the thought of asking for his help did not even come across the queen's mind.

Suzuki Satoru
Much like his peer, the Elder Coffin Dragon Lord, the Brightness Dragon Lord also happen to share the same negative sentiments as him about YGGDRASIL players. In an alternative timeline, this was shown to be the case when Suzuki learned about the Dragon Lords' hatred and animosity directed at players like himself during his first confrontation with it. He harbors a deep resentment towards players for the past actions they have done to endanger dragonkind to the point of close to extinction.

Trivia

 * Alongside the Goblin King, Brightness Dragon Lord was one of the two non-humanoid beings known so far to have impregnated a human.
 * In the Overlord Bonus Volume, Brightness Dragon Lord fought against Suzuki Satoru which had ended in a draw between the two. According to Suzuki, it was only a draw because he had decided to run away from the Dragon Lord. However, Suzuki notes if that's Brightness Dragon Lord's limit, he was confident of being able to beat him the next time they meet again.
