Once upon a time, there was a man in Africa who was immortal. He lived for thousands of years in what is now modern day Ghana. However, he eventually had a spiritual awakening and decided to walk all around the world, collecting psychedelic mushrooms. He walked all the way to Europe, Asia, and the spider goddess even created a bridge from webs so he could walk to North and South America to look for magic mushrooms. He brought them all back to a sacred temple on his home continent, and he asked the spiders to sing the song of life to the mushrooms, so they could be alive and awaken just as humanity once did from monkeys and golems made from clay. This earned him favor with The Golden Teacher God, who rewarded him with complete mental enlightenment, causing him to physically float and have mastery over all kinds of fungus and the ability to generate psilocybin inside of his brain.
The people created by the mushrooms were mushroom people, and they went to the astral planes to build villages and spread spores all over the spirit world. They built many homes from giant mushrooms, but many of their cities were destroyed by war or wrong levels of humidity. Most of them continue living in caves but some more aggressive mushrooms have occupied cities and created massive plantations of mushrooms that they give to the other people in the underworld. There is not a single city in the astral planes where magic mushrooms cannot be found due to the influence of the mushroom people, and even in the city where the king of heaven rules over all of existence, there are said to be magic mushrooms growing in the most clandestine places.
You can call upon mushroom people for spiritual guidance or have spirit companions that are mushroom people. Their villages are too small to have the names known, but some mushrooms are occupying cities previously ruled over by other spirits for those who want warrior mushrooms as their companions. Mushroom people can help you find magic mushrooms in your life and to have your mind opened in comparable ways to the substances. They can also help mushrooms or similar plant life to grow in your environment.
