Did You Know?


The lichen Letharia vulpina exists, but it does not grow naturally on rock, as suggested in the show. The natural habitat of L. vulpina is the dry bark of conifer trees (pine, spruce etc). See more »


Kira: In all of the stories, kitsune are tricksters. They're mischievous. They don't really get caught up in right or wrong or even understand it.
Scott McCall: What's that mean? It's just doing this for the hell of it?
Kira: No, there was something else I found. If you somehow offend a nogitsune, it can react pretty badly.
Scott McCall: How do you offend a nogitsune?
Kira: I don't know. But if it's doing something this bad, then someone really, really offended it.
