Matt dies an unremarkable death only to find himself at the mercy of a reincarnation wheel. Expecting a heroic fantasy life, he is instead reborn as a Tree in a world caught in a relentless cycle of demonic invasions and hero summonings. As a sentient plant, Matt (who eventually takes the name Aeon) cannot move, but he can grow. Over decades and centuries, he leverages a LitRPG system to develop roots that span continents, magical fruit that grants powers, and a network of loyal "Valthorns" to act as his hands. While heroes are summoned every ten years only to die in battle, Aeon plays the long game. He evolves through various stages—from a simple spirit tree to a world-spanning divine entity—slowly turning the tide of the eternal war by becoming the foundation upon which civilization survives.
