Rhongomyniad

Rhongomyniad: The Spear That Shines To The Ends Of The Earth is the holy lance of King Arthur that was used in her final battle to kill Mordred. It is said that no matter the toughness of Mordred's armor, it amounted to nothing before the lance as it pierced her chest. King Arthur also used this spear against Vortigern in his Dragon form, the spiral light of the spear pierced through the heart of the crucified dragon.

Its purpose isn't meant to be used as a weapon to strike down external invaders. It exists to be the planet's anchor and to ensure the World's stability.

The ability to use it has been passed down in a line descended from relatives of Arthur, currently held by Gray. When activated, it can launch a beam of light.
