The planet Earth is where most of the action of FAW takes place. It is set in an indeterminate yet modern time period. Not much more can be said about it, The Main Wiki's article about Earth should be enough.
Not Able PlacesEdit
Due to the authors' amateurishness, action is not really bound to the real geography of Earth. The team back in its time did travel, but its exact location was never told - it was just generic forests and the like. Some of the places mentioned in the story in actuality are "somewhere in Florida", "Waterford, Ireland", "London", "Dallas" and the like, but geography is a loose guideline at best.
