"So, Elder Zora and his race have destroyed their own planet?"
[That is correct. Due to their over-mining of their planet's natural lithium resources, over-extracting petroleum, and an overabundance of waste in their water—they were forced to evacuate their planet and create an artificial mechanical planet.]

It's just a prank, step queen.
