Song of the Symbi

Human colonists from a distant star discovered a large planet covered in dense nutrient-rich fluid with a thick exotic atmosphere and attempted to terra-form it using machinery lowered into the dense jungle. Genetic research led to the creation of humanoids whose bodies leeched off the nutrients in the exotic atmosphere and waters to feed, heal and breathe. These altered humans were called Symbi (from ‘symbiotes’). Centuries after the colonists departed to wage war in a distant galaxy, the Symbi remain, awaiting the ‘Gods’ return. (publishers blurb)
