As Descendants began their work in earnest, humanity was able to expand their territory to beyond the land that had been taken from them. Within that land were the historical cities that once housed kingdoms.
The "King's Guard Lance" is a weapon that was created out of a relic discovered by an exploration party on a military reconnaissance mission. The royal spear used in the creation of this weapon was discovered in the ruins of an ancient royal palace. When it was discovered that the red jewel inset in the spear could absorb an incredible amount of energy before emitting strong shockwaves into the air, it was developed into a weapon.
Upon analysis, this red jewel was found to be made up of components unavailable in Ingris. Its origins are still unknown.
