Dimension Lost

Dimension Lost, also known as the Fog of Extinction, is a top-tier Longinus wielded by Georg of the Khaos Brigade's Hero Faction. It is ranked among the top four Longinus.

Summary
One of the thirteen Longinus, the Dimension Lost is considered to be one of the biggest "bugs" in the Sacred Gear system, having world-class powers that can destroy the world when used by certain users. The Dimension Lost was used by the Hero Faction's Georg until Volume 12 when Indra confiscates it from him.

Appearance
It can be said that Dimension Lost's true appearence is the mist that it creates as the mist is the only proof that it exists.

Abilities
Dimension Lost has the ability block any attack using the mist it creates, and can transport anything inside the mist to any location. Though it has no offensive abilities, once the mist reaches the scale of countries, it can transfer an entire country and its people into the Dimensional Gap to be destroyed (though Azazel mentioned that none of the previous users reached that level). As a top-tier Longinus, it has the potential to destroy the world.

Dimension Create
Dimension Create (霧の中の理想郷-ディメンション・クリエイト- Dimenshon Kurieito), also known as the Utopia of Mist, is the Balance Breaker of Dimension Lost that allows Georg to convert the mist into a barrier to trap his opponents in a different space. Dimension Create can also create various barrier devices as the owner wishes.

Trivia

 * In the Afterword for Volume 9, the author revealed that the Dimension Lost, along with Annihilation Maker, have world-class powers, being capable of destroying the world when used by certain users. Thus earning them a spot as top-tier Longinus.
 * Sun Wukong stated that Georg should "start a dialogue" with Dimension Lost, like how Issei and Ddraig had developed a relationship, to increase Georg's ability to harness Dimension Lost's power.
 * This suggests that Dimension Lost may have some kind of conciousness or will within it. If so, this has yet to be confirmed in canon, and the nature of it is unknown.
