Besides being XIV's equivalent of crude oil. Does anyone think it's more than just that? Considering that the Blue Mage storyline has us stopping a guy from telling parties that would be interested that there's a huge amount of it in the New World. A lot of the time something that's used as an oil/energy source there's normally an unknown consequence in using it.

The most known one being Mako energy being the literal life blood of the planet. In some of the older ones using the various elemental crystals as energy sources ended up over time draining them and making the planet wither.
