What is this place???

During the main scenario you collect different aspected crystals, even if its corrupted it can have an element.

I'm fairly certain that the orange crystal appearing throughout the land is the very same corruption indicated by our Aetherytes turning orange back during the end of 1.0, and furthermore is unrelated to the unique, small elemental crystals collected by the protagonist as part of the main story line.

I've not done Pharos Sirius yet, but the video I watched on it suggested crystal corruption to be a recurring theme within the dungeon with no apparent indication of a fire aspect.

Replay the scenario, a guard obtains piece of the crystal from phario sirius and gives it to you. Also you found a piece of wind aspected crystal in burning wall, and all of it was orange.
