Lillias's Scheme

After dinner with the Delarosas ended, Linetta guided Vaan to their library with a flushed face, still embarrassed by her mother's teasing.

On the other hand, Lillias didn't accompany them; she left on her own, heading off somewhere else.

…

Inside the private library, Vaan stopped by the exploration section and started perusing books related to Perilous Lands.

The Thousand Fog Mountains was one of the largest Perilous Lands in the seven witch kingdoms, but it was not the largest.

In fact, it was the Great Ashfallen Forest.

Ever since Gehenna's Gate appeared inside the Great Ashfallen Forest, access to the northernmost parts of the Pangea continent had been cut off.

That said, the Great Ashfallen Forest was a vast wilderness even before the appearance of Gehenna's Gate. Few had ventured into its depths, let alone pass it.

Thus, little to nothing was known about the northernmost region.
