Nature spirits resemble a floating skull with a handful of segmented tails. They are usually friendly and playful; they speak little, but giggle a lot.
"Being led by nature spirits to get somewhere is a tricky business. The bigger spirits don't like to leave their homes, and the smaller ones seem to enjoy your company too much to just lead you to where you want to go."
— Cyma, traveller
Nature spirits don't die when their home is destroyed, but they will be grumpy about it. I wanted Genius Loci to be largely free of religious conflict, and turned to animism. On Kitas, people apologize for destroying natural landmarks or killing animals; the spirits in turn don't take revenge (usually). And of course the kodama spirits from Princess Mononoke were an inspiration. Threr is only one spirit per tree in Genius Loci, though.
