Blight

Rough Draft - Technovirus faction, devours metals and materials and spreads. Can turn raw material into horrifying monsters to protect itself while it continues to spread.

Will spread throughout planet before exploding the planet like the spores of a mushroom, spraying trillions of small, super dense fragments in all directions throughout space.

Weak to extreme heat, needs to be melted down before it spreads too deep into the planet.
