The Labyrinth

Description
Back during the war, when the monsters were being sealed away, the wizards cast another spell. One that separated the Underground from the rest of Earth. The only way back to Earth was blocked by a treacherous labyrinth, one that contained traps, threats, and a powerful and dangerous creature known only as "The Guardian". The monsters desperately attempted to get through the labyrinth, to the switch that would send them all back. But with every 4 monsters that went in, only one made it out.
