Volcanica

Volcanica (ボルカニカ), also known as the Divine Dragon, is a key figure in the sealing of the Witch of Envy 400 years ago. He is also the guardian of Lugnica and worshiped by its inhabitants. Mentioned throughout the series, he formally debuted during the climax of Arc 6 as a supporting character and minor antagonist.

During arc 6's climax, he acted as the overseer of the third trial of the Pleiades Watchtower and the final obstacle preventing Emilia from conquering it. It's also revealed that decades neglect caused the Divine Dragon's mind to break, reducing him to a shell of his former self.

Appearance
Volcanica is an enormous dragon who's covered in shiny pale blue scales which are said to gleam like jewels and seem sharper than a forged treasured sword. His thick paws are equipped with black, rock-like claws. Volcanica's face greatly resembles that of an Earth Dragon with two large milky-white horns sticking out of each side of his head. Finally, Volcanica has a pair of intelligent looking gold eyes which emit a wise and awe-inspiring aura. His presence is so great that one feels like he isn't even allowed to breath without the Divine Dragon's permission. Another notable feature is the presence of a mysterious white scar located directly underneath Volcanica's jaw. When touched by someone other than Volcanica, the dragon will fall in a state of shock and will desperately try to kill whoever touched it.

In his crouched position, he is said to be about 16 meters in height but his actual size is unknown, though he is much much larger than Valgren who was about 10 meters tall.

Personality
In complete contrast to his reputation, by the time of Arc 6, Volcanica is suffering from a condition similar to alzheimer's, constantly repeating himself and forgetting things. His condition is nothing physical, though, but rather "spiritual death". The Guardian Dragon has lived for so long that everything has lost meaning to him, though he still feels obliged to uphold the covenants he forged with Lugnica and Flugel respectively.

Before falling into his current state, Volcanica was mentioned to be a cynic by Shaula. During his fight with Valgren, about 50-years before the main story, he was mentioned to feel pity for the state in which the black dragon had ended up in, implying he had a sense of pride.

Volcanica speaks in a deific manner favouring the archaic pronouns thou (汝 nanji) and mineself (我 ware) and his voice conveys his omnipotence.

History
Volcanica is a Divine Dragon who several centuries ago made a covenant with Farsale Lugnica to help safeguard and guide the country in times of turmoil. For this reason he is worshiped as a national deity and became the new symbol of the royal family. Lugnica itself is also partially named after him in full "The Dragon Kingdom Lugnica".

Volcanica is said to have met Reid Astrea and Shaula in Flanders, a major city located in southern Lugnica, and blessed the grounds of Flanders so Earth Dragons would be born.

Over 400 years ago, Sekhmet drove Volcanica past the Great Waterfall just so she could rest, causing a fight to occur between the two with Sekhmet falling from the Great Waterfall while fighting, concluding with her death.

During the events with Stride, Volcanica appeared because of its contract with the Lugnican royal family and healed the wounds of all survivors, including those who were at the brink of death and extinguished the burning fires.

Abilities
Vast Intellect: He has enormous knowledge and possibly foresight to foretell the future. However, due to his great age, he currently displays symptoms of Alzheimer's, forgetting certain memories.

Divine Mana: Volcanica has an enormous amount of mana in its body and is even able to cleanse the world with it. The effect is enough to turn off the flames or spread them throughout the city or to cure injured people all at once.

Purification Breath: The dragon's breath, which when let loose rushes straight forward to its target enveloping it in a bluish light. When the light envelops its opponent, the opponent is instantly turned into dust, as if they had been purified. Volcanica used this attack against Valgren to put him to rest.

Great Power: As the Divine Dragon and the safeguard of Lugnica, Volcanica has considerable power. He was able to defeat Sekhmet, the second strongest Witch after Satella, and is stated to even be able to put up a good fight against Reinhard while the latter uses the Dragon Sword. In the present, he has shown to be able to easily overwhelm Emilia while being 90% unconscious and could even destroy Satella's shadows with his purifying breath.

Flying: Being a dragon, Volcanica has a pair of wings which help him to fly. According to Emilia's observations however, Volcanica flies in the same way Roswaal and Puck do i.e. using magic, rather than by flapping his wings. Instead, he uses his wings to glide and control the direction of flight.

Trivia

 * Despite common knowledge, Farsale was not the one who directly made a covenant with Volcanica. He used a young maiden as as a mediator between the Divine Dragon and the Lion King. The maiden was known as the Dragon Maiden.
