Generally, these referred to Spirit Realms that had been fused with Earth for over ten years.
After long-term management by Professional-level Trainers stationed in the Spirit Realm, the Pokémon within had adapted to humanity's presence and behaved in a friendly, affectionate manner.
Major Pokémon schools often used high-safety zones as examination grounds for wilderness survival tests.
Some high-safety zones even allowed ordinary people to visit, sightsee, and interact with Pokémon at close range.
The Changbai Mountain Tianchi Safety Zone, where this examination was being held, belonged to the third category.

The school-issued overcoat was a classic navy blue style. Roy wrapped himself in it as he stepped off the plane, yet the biting wind still sent a shiver through his entire body.
