Lacour Hope

Lacour Hope is a Heraldic cannon powered by an energy stone, created with the intention to halt the advance of the Sorcery Globe's fell beasts. It is devised and constructed by an assembly of Lacourian royal researchers, based out of the laboratories in Lacour Castle.

Because the weapon is powered by Heraldic signs and activated by energy stones, the Lacour Hope is classified as a Quadratic Sphere along with the Sorcery Globe (albeit, a much less powerful one), and the required energy stones are a Quadratic Key.

After an attack by Shin at sea, most of the Lacour Hope was damaged and rests at the bottom of the ocean between Lacour and El, while the energy stones were stolen by Shin and taken to Eluria Tower. In an interview with lead writer, Yoshiharu Gotanda, the developers confirmed that Shin's attack upon the Lacour Hope was not one of survival, but one to steal the necessary energy stones found inside the weapon, confirming that the energy stones are Quadratic Keys.

Story
The party first encounters unidentifiable pieces of the Lacour Hope in the basement of Lacour Castle, but scientists throw the party out. Later, the King of Lacour reveals the nature of the project to the party, and the King and Leon D.S. Geeste (the project head) admit they require an energy stone to power the cannon. Leon and the party then delve into the Hoffman Ruins and secure such a stone.

Later, the Lacour Hope is brought to the Lacour Front Lines, protected by the King's guard. When the horde of enemies of El begin their advance across the ocean into Lacour, the cannon is unleashed. A single, overwhelming cannon fire is sufficient to destroy the entire horde. The army rejoices and the Lacour Hope is loaded aboard a ship, to be taken to El to wipe out the remaining monsters. The final status of the Lacour Hope is uncertain. Shin, right hand of the Ten Wise Men, ambushes the fleet. He destroys the fleet and the Lacour Hope sinks to the bottom of the sea.
