[quote=@Prince of Seraphs] Beware, it's Rouge's distant cousin Shutler. [/quote] No it's... basically microscopic lacrimas surgically infused with a person's body to so they can perform magic based on the lacrima that was infused. Individuals with these are called Metas and there are only four people that given this power. But instead of gathering ethernano, the individual simply has to absorb the surrounding environment that relates to their infused lacrima (kinda like a solar panel), this also helps when trying to to heal or recover from something. But the user is only powerful when they're in their element. Once they're outside of it where it's scarce, they're weaker and have to rely on their storage inside them. But it's also because of this weakness that not being proved their element for a long enough time or overly exposed to an element that opposes them can't significantly hurt them. Another fact is that when an individual is using their ability as a tool or weapon, it's an extension of themselves, allowing them to control the behavior or help sustain it's existence. No one knows about this except for a few people.
