Deep Darkness Dragon Lord

Deep Darkness Dragon Lord (常闇の竜王) is a member of the Dragon Lords, the most powerful dragons in the New World.

Background
Deep Darkness Dragon Lord is a dragon lord who did not enter the war against the Eight Greed Kings. It is not certain this means the Dragon Lord was born after the battle or simply it ignored the war. Either way, it is still alive until the present time. The Deep Darkness Dragon Lord is dwelling in a large subterranean cave without going outside, so the Platinum Dragon Lord doubted whether it will help the fight against new hostile existences from YGGDRASIL.
