Catastrophe Dragon Lord

Catastrophe Dragon Lord (破滅の竜王) is a member of the Dragon Lord, the most powerful dragons in the New World.

Background
It seems that this dragon lord is already dead, as the "Thousand Miles Astrologer" of the Slane Theocracy predicted its revival.

Chronology
When it was predicted to be reviving, the Slane Theocracy had dispatched the Black Scripture, one of the six Scripture to prevent it from happening.

Abilities and Powers
The Catastrophe Dragon Lord's power is unknown, but it should be noted that the Archbishops sent all thirteen members of the Black Scripture to defeat the dragon lord, which speaks volume of its power.
