First time posting a new thread! Yay!

Going through Cutter's Cry, I couldn't help but notice how the last part starts to become full of glowing blue rocks and vents of blue steam. We know this is the telltale sign of raw Ceruleum, and it makes sense. The entrance to Cutter's Cry is in the Northern part of Central Thanalan, so this part probably goes well into the Ceruleum-ruch Northern Thanalan.

But what are the RED rocks?

The blue Ceruleum gradually gives way to a glowing red rock that isn't as dangerous (doesn't act as a hazard) but I can't help but feel like it might be important somehow. It's not your standard red crystal, as no other crystal glows quite the same shade. What is this stuff?
