original passage: A pioneering work of the fantasy genre was "The King of Elfland's Daughter", a 1924 novel by Lord Dunsany. The Elves of Middle-earth played a central role in Tolkien's legendarium, notably "The Hobbit" and "The Lord of the Rings"; this legendarium was enormously influential on subsequent fantasy writing. Tolkien's writing had such influence that in the 1960s and afterwards, elves speaking an elvish language similar to those in Tolkien's novels became staple non-human characters in high fantasy works and in fantasy role-playing games. Tolkien also appears to be the first author to have introduced the notion that elves are immortal. Post-Tolkien fantasy elves (which feature not only in novels but also in role-playing games such as "Dungeons & Dragons") are often portrayed as being wiser and more beautiful than humans, with sharper senses and perceptions as well. They are said to be gifted in magic, mentally sharp and lovers of nature, art, and song. They are often skilled archers. A hallmark of many fantasy elves is their pointed ears.
original sentence: Tolkien also appears to be the first author to have introduced the notion that elves are immortal.
sentence2: Based on the way this passage describes Tolkien's characters, if an elf were to die in one of these stories, could the reader assume that the death came about as a result of sudden injury in battle, as a result of grief, or perhaps due to some other cause that humans would call "untimely"?
