They say there once was a giant called Tabuarariki, and his footprints can be found at several locations, only a few of which are in Beru. However, he is said to have chosen Beru as his home world in his later years. Many lands claim their island (or continent) was once his his personal property.
The newer lore masters call some special landmarks "Craters", while others call them "The Footprints of Tabuarariki".
