Setting:

Welcome to the Endless Labyrinth, a magical realm that serves as the afterlife for countless souls who have left their mortal lives behind. This realm is filled with endless tunnels and chambers, each one more unique and unpredictable than the last. The vast expanse overhead opens into an eternal, bright void that seems to stretch on forever.

Story Premise:

The players begin the game as newly arrived souls in the Endless Labyrinth, each having left their mortal life behind due to some unfinished business, great regret, or a desire to seek redemption. A mysterious entity known as The Keeper of the Labyrinth informs them that the only way to achieve their goals and find peace is to journey through the Labyrinth, delving deeper and deeper into its mysteries.

The players are Soulbound, spirits tethered to the Labyrinth who possess incredible magical abilities but are not truly physical beings. This allows them to adapt and evolve as they journey deeper into the Labyrinth, enhancing their abilities, gear, and even their spiritual forms. The players will need to explore, interact with various inhabitants of the Labyrinth, and overcome challenges and enemies in order to progress.
