Mycus

"these are the Mothers, the holy mothers of us all, The Chosen of the Scape, She watches over us, and we carry her blessing within us, she creates the very air, and the ground we walk upon. We are truly indebted to our goddess"

Description
The Mycus is a complex Lichen, mixing both plants and mushrooms. The smallest Mycus is a metre cube, and sentient, but the largest is the City of Galatea, which spans underneath the entire city and carries great wisdom. Their spores can be used as lights for lamps across town, They will also absorb waste, either rotten or newly made in a form of waste disposal, while the fact it's a lichen and not a true fungus means it actually enrichens the soil, causing the relationship with humans to be symbiotic.

Spores
The Spores of a Mycus can latch into a living being and become part of them. Only humans have been shown to survive this process. The human then feels a deep sense of calm and belonging, and can be healed by the growth of the Mycus within them.

Galatea
The most well known Mycus is the city of Galatea, one of the Twin Cities.
