Parent location: Corrupted Earth
Laggion was constructed some time after the Great Corruption. Originally intended to be a camp for the demons investigating the cataclysm, it eventually grew into a village, then a city, and now a metropolis as more and more demons decided to move there and settle on Earth.
It is home to the Magic Institute of Laggion, which focuses on studying all the types of magic found on Earth, both before and after the Great Corruption.
