World Tree

The World Tree is a colossal cosmic structure, its roots anchored deep in the Sea of the Afterlife and its trunk stretching across the fabric of the universe. It is far more than a mere tree — it is a fundamental mechanism created by the Absolute Being to regulate the cycle of souls.

The souls of the dead wander the Sea of the Afterlife until they are absorbed by the World Tree's roots and drawn up through its trunk. In its branches, unique fruits ripen, and within these fruits souls are purified of the burdens of their past lives. Once cleansed, they are returned to the living worlds to be born anew, perpetuating the cycle of reincarnation and maintaining the balance between life and death across all dimensions.

Beyond its role in reincarnation, the World Tree is the wellspring of the Rulers' heavenly armies. The fruits brim with pure energy and can be transformed into powerful soldiers who fight against the Monarchs. In their eternal war, whenever the Monarchs gain even a slight upper hand, the Absolute Being harvests the World Tree's fruits, instantly replenishing the Rulers' ranks and restoring equilibrium.

Thus, the World Tree stands as a cornerstone of the cosmogony in "Solo Leveling". Without it, the cycle of reincarnation would collapse, and the struggle between the Rulers and Monarchs would inevitably tip in favor of chaos and destruction. It embodies the link between the afterlife and the world of the living, as well as the Absolute Being's will to uphold order across the universe.
