Undertale Worldview + The Underground

This is a lorebook related to the Undertale Underground. It also includes the roadmap found in Undertale Yellow.

One day, war broke out between the two races.

After a long battle, the humans were victorious.

They sealed the monsters underground with a magical spell.

Many years later...
