So most of the material I've read about other planets in the pathfinder universe makes it clear that not everyone knows there is alien life and portals to other worlds, but that there are many legends surrounding the concept.
I'm trying to come up with and collect legends explaining portals to other worlds, life on other planets, etc. - legends that contain at least some small element of truth surrounded by speculation and tradition.
Does anyone have anything they've run across or thought of that they'd like to share?
