Warble

In a fractured reality divided by an impassable boundary, humanity resides in the Overworld while demons rule the Underworld. These two distinct realms have long existed in isolation from one another, separated by a divide that makes crossing between them seemingly impossible. The delicate balance of this dual existence is maintained only by the strict separation of its inhabitants, keeping mortal civilization far removed from the dark territories controlled by demonic forces. However, when circumstances demand passage across this forbidden threshold, there exists only a single method for humans to navigate between the two realms. This solitary path represents far more than mere travel; it stands as mankind's ultimate lifeline against impending doom. Known as WARBLE, this extraordinary means of traversal carries the weight of human survival on its shoulders. As threats loom and the boundaries between the Overworld and Underworld grow increasingly perilous, WARBLE emerges as the final hope for a species fighting to endure in a world shared with demons.
