"She lives the life many dream of. Fame and fortune, yet she shares that with her home, Aireon City by making improvements using her money. A generous soul. Many people could learn a thing or two during a battle with her."

With large trees and relatively calm weather, Soloran Forest is just outside of Aireon City. It's large trees seem to form a barrier to the harsh winds that can plague Aireon, allowing Pokemon to dwell in the forest.
"Nature works in many ways. During the battle between Zekrom and Reshiram, they formed Morningdew Valley and the Fogbound Lake. But these trees, they created a home for the pokemon to thrive in. It wasn't a cataclysmic battle, just some tall, thick trees."
- Professor Willow on the nature of Minoru and it's areas, Chapter 10.
