Descriptions
In the Ley Line memories, it was once a pioneer in stellar exploration, and the massive weapons it once possessed have been deeply imprinted upon this place, resulting in a terrifying foe that all challengers must face...
The turbulent data within the Ley Lines has made its core become more violent, causing the detection devices it oversees to unleash energies more calamitous than they originally would.
As the Ley Line disturbance has warped and corrupted it over time, its core and detection devices have become completely overwritten. The original purpose for which it was designed is all but gone. All that drives it now is a destructive will that drives endless machine hordes forward to drown all life.
In the Ley Line memories, its corrupted form endures like a wound that never heals, consuming all life that dares to stand against it...
Twisted by the turbulence of the Ley Lines, its foul power has grown stronger, forming sharp claws that carve indelible marks into the earth's defenses.
Driven by the turmoil of the chaotic Ley Lines, its frenzied, delirious whispers have been honed into a cutting edge aimed squarely at rending the world's hard-won order atwain...
In the Ley Lines' memories, it was once thrown into battle as a war machine. This past makes it a massive threat even today.
Amidst the flowing Ley Lines, the golden inscriptions within it have been twisted and deformed, and now constantly input this incorrect command: "Slay all you see."
Amidst the turbulent flood within the Ley Lines, its lava-resistant shell has been transformed into armor, the great might that built colossal cities now forged into titanic pincers. What was once a command to "construct" has been warped into a desire to "destroy," driving it to complete the "grand endeavor" of rendering all things into rubble.
