Dragon Lord

Dragon Lord (ドラゴンロード) is the title for the most powerful dragons found in the New World. They are considered to be one of the strongest beings in existence alongside Players and their descendants, God-kins.

Background
The position of Dragon Lord holds a special significance among Dragons. It is a title only given to those who have either reached the highest age category amongst their kind (Ancient), possess special powers, or can use exotic magic. In the Web Novel, other Dragons treat the Dragon Lords with respect.

Age of the Dragon Lords
Six hundred years ago or even further back, there was a time known as the "Age of the Dragon Lords". Back then, the Dragon Lords were considered to be the rulers of the New World, ruling it through the use of their Wild Magic.

Eight Greed Kings
Around 500 years ago, a war broke out between the Dragon Lords and the players known as the Eight Greed Kings. Unfortunately, the Dragon Lords lost and their rule came to an end.

On the other hand, the rule of the Eight Greed Kings didn't last very long, as they had a fallout with each other that resulted in them killing each other. With the demise of these players, Platinum Dragon Lord then took residence in their floating castle thereafter. He did so as a way to guard their powerful magic items from falling into the wrong hands.

In addition, it seems that the Slane Theocracy had also been hunting them down in its campaigns against non-humans. For instance, the Theocracy's supposed attempt to subjugate Catastrophe Dragon Lord.

At around the same time, the arrival of Tier Magic corrupted their use of Wild Magic, causing the Dragon Lords to lose the ability to cast it properly. Tier Magic was first introduced by the first known players to arrive in the New World, the Six Great Gods, and was later spread even further thanks to the efforts of the Eight Greed Kings.

Evil Deities
The majority of the surviving Dragon Lords did not seem to get involved in the battle against the Evil Deities. However, the Platinum Dragon Lord had allowed the Thirteen Heroes to take some of the magic items of the Eight Greed Kings to aid them in their battle against the Evil Deities and even joined the group by controlling an empty set of armor and attacking the Evil Deities from a distance using magic.

Present Day
Fortunately, there were Dragon Lords who survived the purge of their species by the Eight Greed Kings, as some of them did not bother to participate in the war effort with their fellow dragons. Nearly extinct in the present day, the surviving Dragon Lords have gone into isolation.

Though some have remained at least somewhat active from time to time. Platinum Dragon Lord continues guarding the items of the Eight Greed Kings while Brightness Dragon Lord's founding of the Dragon Kingdom, but has now gone into hiding. In other instances, there was Heavenly Dragon Lord who kept flying around in the sky and Deep Darkness Dragon Lord holing up in a giant cave underground. There were also Dragon Lords, including the Platinum Dragon Lord, serve as the highest authority of the Argland Council State.

The Undead King Arc
It was mentioned by Nigun Grid Luin while the Sunlight Scripture was attempting to assassinate Gazef Stronoff, that the Black Scripture was dispatched for the upcoming resurrection of Catastrophe Dragon Lord along with the protection of a World Item.

Moreover, there happens to be a brief mention of three magical items that were unimaginably powerful in the New World. One of these items came from the Dragons, who were once the masters of the world before they were decimated by the Eight Greed Kings. The most powerful Dragons, the Dragon Lords, are said to have made these items.

The Dark Warrior Arc
Clementine told Khajiit Dale Badantel that if secret information about Zesshi Zetsumei were to be leak, it would lead to total war with the surviving True Dragon Lords. At the same time, it could possibly drag the Slane Theocracy into the kind of war where they might likely get destroyed in the crossfire.

The Sealed Evil Tree Arc
Pinison Pol Perlia believes the potential candidates out there who can likely defeat Zy'tl Q'ae were the Dragon Lords.

The Lizard Man Heroes Arc
Zesshi Zetsumei thought that Shalltear Bloodfallen must either be Vampiric Dragon Lord or Elder Coffin Dragon Lord as she was too strong to be classified as normal vampires of the New World.

The Men in the Kingdom Arc
During the demonic disturbance, Evileye believed that Jaldabaoth was as strong as the Platinum Dragon Lord.

The Invaders of the Large Tomb Arc
A group of workers discussed about powerful individuals they happen to know of and among them, were the Dragon Lords from the Argland Council State. There were some who believed there are only five of them in total, but other people stated that they are actually seven.

Rigrit Bers Caurau traveled to the floating castle of the Eight Greed Kings to visit the Platinum Dragon Lord. While discussing about a new threat that had appeared in the world, Rigrit asked the Platinum Dragon Lord if they should ask for support from the other Dragon Lords. However, he doubted the Heavenly Dragon Lord and Deep Darkness Dragon Lord would aid them and if they could even be able to find the Brightness Dragon Lord.

Later, when a Dragon invaded the Imperial Palace of the Baharuth Empire, Emperor Jircniv initially mistook it for one of the Argland Council State's Five Dragon Counselors, until it was revealed that it belonged to Aura and Mare, whom were sent to enact retribution for the Worker invasion of Nazarick.

The Ruler of Conspiracy Arc
During a conference meeting held in the Slane Theocracy, the Cardinals accepted the fact that Platinum Dragon Lord is not affected by their World Item, Downfall of Castle and Country. Yet they were hopeful and confident enough that the World Item's power will work on Catastrophe Dragon Lord successfully in case it does appear. Moreover, the Cardinals are reluctant of deploying Zesshi against the Elf Country because if they were to carry it out, the group believed it will incite Platinum Dragon Lord to likely respond in kind. In the end, they decided to call for a diplomatic meeting with the said Dragon Lord concerning the elves.

The Craftsman of Dwarf Arc
The White Dragon Lord, Olasird'arc Haylilyal encountered Ainz Ooal Gown in Feo Berkana. Attempting to do battle with Ainz, he was quickly killed by the undead. The Dragon Lord's corpse was later taken into Nazarick for harvesting. His family was later subjugated under the rule of the Sorcerer Kingdom and have since been used as a means of transportation.

Strength
Dragon Lords are dragons who have reached the highest age category known as "Ancient" among their kind. According to the Web Novel, Dragons that are in this stage of their development, have a strength that cannot be defeated by the race of humans. Either that, or there some powerful Dragons that possess special powers unique to themselves.

Very few Dragon Lords to this day can use Wild Magic, which grants them abilities completely different from Tier Magic. However, it seems that the essence of Wild Magic was corrupted by the invasion of YGGDRASIL players, so it is becoming more and more difficult to use Wild Magic properly.

Also, there are some dragons like the Blue Sky Dragon Lord, and the White Dragon Lord, in the New World who have already begun practicing or using Tier Magic rather than their traditional Wild Magic.

If prepared with enough resources and manpower, ten of the True Dragon Lords were potentially strong enough to defeat at least one of the Eight Greed Kings. In a way, this does speak of the volume of a True Dragon Lord's power at its prime, unlike the current kinds at present.

Trivia

 * Worm Dragon
 * A lot of the Dragon Lords were known to have been killed off by players such as the Eight Greed Kings to Ainz Ooal Gown until now. Yet the opposite could likely happen with the Deep Darkness Dragon Lord being the only one known so far who was able to kill a Player in contrast to the opposite happening to him.
 * The Theocracy considered the dragons with the power to use Wild Magic as the "True Dragon Lords".
 * The Argland Council State and the Dragon Kingdom are currently under the rule of at least one Dragon Lord.
 * The Platinum Dragon Lord doubts that the remaining "True Dragon Lords" will lend him military aid against players or even participate in a war against them at present.
