Dragon Lord

Dragon Lord (ドラゴンロード) is a title for the most powerful dragons in the New World. As dragons are regarded as the strongest species in the New World, Dragon Lords are naturally the strongest beings in existence except those from YGGDRASIL.

Background
The Dragon Lords have fought against hostile YGGDRASIL players for a long time. At some point the Slane Theocracy seems to have begun hunting them in its campaign against non-humans. Most Dragon Lords were killed during the war against the Eight Greed Kings. Those who did not enter the war are still alive. Yet, it is not certain whether the present Dragon Lords were born after the battle or if they simply ignored the war.

Nearly extinct in the present day, the Dragon Lords have gone into isolation. Some have remained at least somewhat active from time to time. Platinum Dragon Lord took up the duty of guarding the items of the Eight Greed Kings so no one would ever be able to misuse them. The Brightness Dragon Lord even formed a nation, the Dragonic Kingdom.

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

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

The Lizard Man Heroes Arc
Zesshi Zetsumei guessed that Shalltear to be either the Vampiric Dragon Lord or Elder Coffin Dragon Lord as she was too strong to be classified as normal vampires of this world.

The Men in the Kingdom Arc
During the demonic disturbance, Evileye thought that Jaldabaoth was as strong as the Platinum Dragon Lord and that both of them were over her understanding so the exact power level was unknown.

The Invaders of the Large Tomb Arc
Rigrit Bers Caurau traveled to the floating castle of the Eight Greed Kings to visit her former comrade of the Thirteen Heroes, Platinum Dragon Lord. While they first talked about their time as members of the Thirteen Heroes, their conversation took a more serious turn when they began discussing that a new threat had appeared in the world. Rigrit asked if they should ask for help from the other Dragon Lords. However, he doubted the Heavenly Dragon Lord and the Deep Darkness Dragon Lord would help or if they would even be able to find the Brightness Dragon Lord.

Strength
Some of the Dragon Lords can use 'Wild Magic', which has abilities completely different from Rank 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.
