@Drak: I could have something troll Four right now, if you wish...
Laura holds the metal up against the sun, as the silver-colored piece sparkles. Charlotte speaks however.
"Koltanium is some metal from the Universe where those Vanguards came from. Remember John, Natalie and Vladimir? Either way, this metal is extremely resistant in it's purest form, and almost nigh-invulnerable when it's put into armor. They said that only Koltanium weapons can pierce Koltanium armor... They say the metal is also like an animal, reacting to the environment, and other stuff. What we have here is Koltanium in a liquid metal form, so it can regenerate... If we were to put it into a flame, it could be shaped into a blade or piece of armor... We upgraded our IS mechs with this stuff."
