Later in the game, the party may locate two Pumice Pieces, which can then be forged into Pumice by Hades at his Synthesis Shop in Memoria. Pumice can also be received by beating Ozma, the most powerful enemy in the game. Ark's spell power is equal to 106 plus the total number of Lapis Lazulis in the party's inventory.
When equipping Garnet with the Pumice, she can learn to summon Ark. Its attack is called Eternal Darkness (暗黒の運命, Ankoku no Unmei?, lit. "Dark Fate"), which deals Shadow-elemental damage to all enemies.
It costs 80 MP to summon. Ark is notable for its long attack animation - the full length attack is almost two minutes, and the short animation is longer than most summons' long animations.
Location: Treno, Card Stadium, Chocograph treasure "Forgotten Island".

Ark is fought as a boss at Oeilvert.
- The Pumice item used to summon Ark is known as "Fuyuuishi" (ふゆう石, "floating stone?). In the original NES version of the original Final Fantasy, this item was translated as "FLOATER", and was used to lift the ancient airship from the desert. This bond is strengthened by the fact that Ark takes the form of an airship.
- Ark appears to hold a dueling thematic against Alexander in Final Fantasy IX; both of their elements are opposing, with Ark being Shadow-elemental and Alexander being Holy-elemental, both are mechanical in nature, being feared as ancient weapons and summons, with Alexander being an immobile megalithic castle fortress, while Ark is a transforming airship robot, both appear to have a theme of Heaven and Earth, with Ark being air-borne and Alexander being earthbound, both represent their respective worlds of origin; Ark comes from the planet of Terra, while Alexander comes from Gaia, and both of their names relate with a theme of judgment and punishment, with Alexander known for his attack, Divine Judgment, while Ark's original attack name in Japanese was known as Dark Fate.
