Under the rhythmic beats of the living world, a new rumor was growing among the Cognitive Citadels and the symbiotic explorers: the existence of a biochemical underworld, invisible to ordinary eyes, where the Biological Souls resided — conscious entities formed by evolutionary layers of memory, instinct, and protection.
Called the Deep Neosoma, this subterranean symbiotic world revealed itself only to those whose bodies were in harmony with the three Paths — Biocombat, Biocultivation, and Biomagic. To reach it, the host needed to perform the ritual known as the Descent of the Inner Pulsar, a process of extreme biological introspection where the boundaries between body, mind, and soul dissolved.
At the entrance of Neossoma, the symbiont called Raen-Vü, a pulsating being with an open cortex and reflexive tentacles, led an expedition composed of three entities: Kal-Torr, a cultivator of the Crystal Seed; Maedra, biomage of the Vermilion Synaptic Order; and Ixo'nar, a carnomorphic warrior from the Tribe of Resilient Jaws.
Each island floated in a viscous sea made of liquid synaptogenesis, representing an environment with radically distinct chemical compositions. There was the Sound Selenium Island, where everything vibrated in resonance with the thoughts of the visitor.
The Luminescent Carbonate Island, inhabited by Souls that manipulated optical energy. And the most feared: The Island of Psychic Neuro Acidic, where the slightest doubt in a visitor's heart could generate cognitive distortions that trapped them forever.
But Raen-Vü was not seeking mere contact. He sought fusion. In the depths of an island made of unstable ions and mature neuro receptors, the Biological Soul known as Yural'Thêa awakened. She was ancient - a confluence of symbiotic lineages lost for millennia.
Her body resembled a spiral of lights and ethereal flesh, and her voice manifested directly in the marrow of the listeners."Why do you desire fusion, Raen-Vü?" she asked, touching the most fragile memories of the symbiont."Because my purpose is no longer just to live. I wish to be a bridge between worlds - to become not only a symbiotic body but a Catalytic Soul."Yural'Thêa felt the truth.
And so, the Rite of Symbio Integration began - where host and Soul danced in circuits of experience, reconstructing one another in real time.The fusion was not just symbiotic. It was Bio-spiritual
And when it emerged again to the surface, Raen-Vü was no longer just a symbiont. He had become the first Carrier of the Integrated Soul, an entity that carried within itself the microcosm of the Neossome — capable of influencing minds, healing emotional wounds, and protecting itself and others with the wisdom of a thousand past existences.
And so the world of the Triad would never be the same.
