Worldbreaker had the appearance of a Guardian sized glaive, with the head made of pure Davross and the pole made of Yggdrasill wood. Purified by Leegaain's Origin Flames, its power cores permanently boosted by Tyris' Life Maelstrom, and crafted by Salaark while pregnant.
The glaive was actually an omni-weapon, capable of shapeshifting into every form since Leegaain was proficient with all kinds of weapons. Its enchantments and the Yggdrasill wood complemented his breathing technique, Worldkeeper.
What had been born to protect, the weapon used it to destroy.
"We'll see. I'm still a better fighter than you." Roghar said, and Mogar seemed to agree.
The planet created a Fringe around the two Guardians and sealed them inside.
A normal battle between them would have forced maps to be redrawn, but once Guardian level weapons were unsheathed, Mogar had to prevent the clash from extinguishing all forms of life.
