Midgardsormr (Final Fantasy XIV)

Midgardsormr is a dragon king in Final Fantasy XIV. A legendary king of kings and guardian deity in Silvertear Falls, he led the Dravanian Horde to battle against the Garlean Empire's airship fleet in the Battle of Silvertear Skies, an event that cost the creature its life.

He was seen during the opening CG of the original game release (Version 1.0). This footage is later reused during a flashback narration from Gaius Van Baelsar in A Realm Reborn.

Appearance
Midgardsormr is initially seen as a colossal serpentine dragon, easily large enough entwine around the Garlean dreadnaught Agrius, and could outright destroy lesser airships with powerful energy attacks from his mouth. His corpse remained entwined with the dreadnaught as the ceruleum tanks detonated; by the time the Agrius is explored during A Realm Reborn, the carcass is in advanced stages of decay.

His spirit later takes form of a small wyvern-like minion.

Personality
His personality, as shown by his dialogues with the player, is that of a patient, enigmatic figure. He speaks in a slow, deliberate monotone and exhibits archaic speech patterns. While the original Japanese dialogue unquestionably portrays him as an ally of the player character, the English localization depicts him more ambiguously through his unique use of language.

Story
In the year 1562 of the Sixth Astral Era, Gaius van Baelsar mobilized the airship fleet of the XIVth Imperial Legion to seize Mor Dhona as part of his initial campaign to conquer Eorzea. This act stirred the Wyrmking from his quiescence beneath the lake, and called forth the Dravanian Horde to repel the invaders. As he entwined around the Agrius to cripple the flagship, ceruleum tanks inside the vessel exploded, killing Midgardsormr and causing long-term environmental contamination of the area

For the next fifteen years, his corpse remained entwined with the wreckage of the Agrius in Lake Silvertear, a landmark known as the Keeper of the Lake. As the Calamity and the Seventh Umbral Era came to pass, the Keeper remained a silent testimony to the terrible Battle of Silvertear Skies. Five years after Dalamud fell, Ishgard's astrologians began to see portents in the heavens: the dragon star flared, considered an omen of Midgardsormr's resurrection. This prompted Ser Aymeric of Ishgard's Temple Knights to begin negotiations with the Scions of the Seventh Dawn to request that the Keeper of the Lake be monitored.

Eventually, Aymeric's lieutenant Lucia sent forth a request that the site be investigated directly. With the aid of Doman surveyors, the Adventurer took a boat out to the wreckage, fighting through lake creatures, dragons, and imperial troops from Castrum Centri to reach the top of the Agrius. As they approached the head of the wyrmking, Midgardsormr's spirit awoke and attacked the party.

Once the spectral dragon was defeated, Midgardsormr's spirit continued to speak with the Adventurer. Upon realizing the Warrior of Light was chosen by Hydaelyn, he dispelled the Blessing of Light (rendering the six crystals dim and shattered), and instead bound himself to the Adventurer. Taking the form of a diminutive drake, he declared his intent to watch and "wait."

Trivia

 * Midgardsormr's wyvern form bears a slight resemblance to the wyverns summoned by Dragoons in Final Fantasy XI. It can be summoned by the player as a minion after completing the Keeper of the Lake dungeon.
 * Similar to some other minions, he will perch on the player's shoulder (or player's head, if Lalafell), and occasionally spits out a blue flame in his idle animation.
