Rio and the survivor. By Tea Seroya.

The Secret of El Sol is a feature film set in the Oakwood Universe after the Great Storm.  The story picks up some time after Rio and an unnamed Survivor meet in “Oakwood: Hungry.”  They have been a solitary duo for some time now, fending off packs of storm-sick while continuing Rio’s search for “timeless ground.”  The Secret of El Sol focuses on their adventures after they encounter two more survivors of the storm, a woman named Grace and her son, Nueve.

This movie finishes the story begun in Journey to El Cielo and it is chronologically the second to last work in the timeline so far.  However, since “Oakwood: The Scout” takes place thousands of years after any other currently revealed story, The Secret of El Sol is presently considered the capstone of the Oakwood AD Timeline.
