Introduces a beneficial fungal symbiont — engineered from medicinal mushroom species — that colonizes the skin and mucosal membranes, creating a living biological shield. The mycelial network produces broad-spectrum antimicrobial compounds, accelerates wound healing at colonized sites, and provides an early-warning immune response by detecting pathogens before they penetrate the body. The symbiont is invisible to the naked eye but detectable as a faint earthy scent on the user's skin. In ideal conditions, the mycelium produces barely visible white filaments at wound sites that accelerate clotting and prevent infection — essentially a biological bandage that grows from the skin. Gravemoss Biofoundry engineered the symbiont from Trametes versicolor (turkey tail mushroom) and Ganoderma lucidum (reishi), both renowned for immune-modulating properties.
