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 began hunting them in it's campaign against non-humans. Most Dragon Lords were killed during the war against the Eight Greed Kings. However, some of them, 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, however, remained at least somewhat active. 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 were dispatched for the upcoming resurrection of Catastrophe Dragon Lord along with protecting the World Item.

The Lizard Man Heroes Arc
Zesshi Zetsumei guess that Shalltear may be 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 is as strong as the Platinum Dragon Lord, that both of them are over the estimation of her so the exact power level is still exactly 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 at first talking about their time as members of the Thirteen Heroes, their conversation takes a more serious turn when they begin discussing that a new threat seems to have appeared in the world. Rigrit asks 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.
