The term 'EXTENDED STORIES' can be summarized as SAGAS, which is a five-letter word. SAGAS are long, narrative stories that originated in Iceland and Norway during the Middle Ages. They often involve heroic characters and mythical creatures, and are usually set in a distant past. SAGAS were traditionally passed down orally, but were eventually written down and published. They are still popular today, and have been adapted into films, television shows, and other forms of media.
