Mammoths roam the plains of Whiterun. They are peaceful creatures who ignore everyone else unless someone attacks them. J’Zhirr guess one can be indifferent when one is so big. There is nothing much in the world which can hurt them. This means that one can get really close to them without fear of coming under attack. However, giants herd the mammoths so J’Zhirr is careful not get too close lest one is nearby.
