Ceruleum

Ceruleum is a powerful yet highly unstable and flammablehttps://ffxiv.consolegameswiki.com/wiki/Boom_Goes_the_Ceruleum source of energy in Final Fantasy XIV, mainly used by the Garlean Empire to power magitek engines. The Empire consumes vast amounts of it to power anything from airships to armored tanks. In contrast, Eorzean citizens mostly use ceruleum to just power their airships.
Though it is abundant on continent of Ilsabard, in Eorzea ceruleum is only found in a small swath of mountainous land in Northern Thanalan. These ceruleum deposits are monitored and controlled by the Amajina & Sons Mineral Concern of Ul'dah, as it fell within the city-state's land and they recognized the potential value of ceruleum. Ironically, before Gaius van Baelsar invaded Eorzea, the imperial army was the Concern's biggest customer. The XIVth Imperial Legion has installed a competing mining facility near Castrum Meridianum. As evaporated ceruleum produces a blue haze, the region became known as "Bluefog" due to the perpetually tinted sky.
Ceruleum is volatile and must be handled with care. It attracts voidsent grenades that can easily ignite it. Security is high near any facility that processes the fuel. During the Battle of Silvertear Skies, as the imperial flagship Agrius fell in confrontation with the Dravanian Horde, its ceruleum tanks reacted with aether released from the dying Midgardsormr, which crystallized Mor Dhona's landscape.
In the alternate timeline where the Eighth Umbral Calamity ravaged the land, ceruleum was affected by Black Rose, and was rendered useless as an energy source.
The territory of the Whalaqee tribe on the continent of Tural, across the sea to the west, is extremely rich in ceruleum. The area known as Lapis Canyon, which glows blue because of all the ceruleum there, is sacred to the tribe. The recent discovery of ceruleum deposits in Tural's Shaaloani region has led to recent industrialization there to mine it.
Not long after Emperor Varis was murdered by his own son, Zenos yae Galvus, the Empire descended into civil war. As a result of the imperial legions tearing Garlemald apart in their efforts to achieve their own interests and subsequently falling under Telophoroi control, the price for ceruleum has shot up all across Eorzea.
Curiously, Hildibrand Manderville described the crater on the moon that once held Zodiark as a natural wellspring of ceruleum.
