Ytaleh are a coiling mist of nervous tissue, beautiful and strange. Evolved to drift in the gelatinous depths of their world’s oceans, they are almost helpless on dry land. As they evolved, their species developed the ability to infiltrate another creature’s body, binding to its nervous system and guiding their actions. Now able to explore the world, build and experiment, the parasites developed an advanced society with galactic reach.
Modern ytaleh are no longer parasites but symbiotes, co-evolved with certain other species, neither able to survive without the other. Their host species develop only rudimentary brains and nervous systems, relying on the ytaleh to be their minds, while they are the hands. Scaled ytaleh-igophi dance in the oceans, great fins beating through the waters as they explore the depths. The ytaleh-horoth scamper through forests, and the ytaleh-affah lumber on the plains. Even the skies echo to the song of swooping ytaleh-barra. Each pairing-caste brings its own strengths and insights to the greater ytaleh civilisation.
