After another three wrong guesses, I'll give you the fourth clue:
1: This song's title is very similar to the title of a song by a band that has been Maiden's support act after the year 2000
2: This song also mentions a geographic location.
3. The lyrics contain a word that, to my knowledge, is not used in any other Iron Maiden song.
4. The title (and topic) of the song has also been the subject of many works of art.
Already guessed: Fear is the key, The Prophecy, Speed of Light,Strange World, The Fallen Angel, Tailgunner, Revelations, Moonchild, The Talisman, Isle of Avalon
