Nano's, the very thing that once destroyed civilization in the universe, are now used as cybernetics. Cybernetics are applied via a pill made of nano's. Once you've swallowed it, the nano's replace certain organs with mechanical variants. These cybernetics can grant things like increased strength, intelligence, resistance to poison and disease, or even immortality. Cybernetics are an omnipresent phenomenon in Zeloria, as nearly everyone here is a cyborg.
