Bio Dungeon: Symbiote

In the harsh northern landscape, young orphan Marstin Hardgrove learns to survive through thievery, but when a job goes wrong, he finds himself at the mercy of the Thieves’ Guild. Left for dead after swallowing a unique dungeon crystal, Marstin is thrust into a microscopic world where the crystal, initially confused, becomes determined to take over the living being. To achieve this, it must navigate hostile pathogens and the body's immune defenses, ultimately striving to transform the very organism into its own Bio Dungeon. This adventure features elements of LitRPG/GameLit, blending character progression and scientific insights into the immune system's battle against invaders.
