>>56447630To put it shortly, Self replicating and mutating crystals that arrived on a meteor that fucked up the earth in the Command & Conquer universe. It was discovered near the Tiber river, hence the name "Tiberium", it was also a miracle material that could be used for pretty much anything if processed correctly.
Kinda how Terapagos arrived on a Meteor and made Tera Crystals (that i think there is a line that mentions are slowly spreading)
