Clue 1:
A single line in this song nods to two Maiden album titles.
Clue 2:
Both in the song title and the first line of the song you'll find literary devices at work.
Clue 3:
The song is an album track. No other song on the album share the same writing credits.
Coming to the realization that I can't see for sure: Dream of Mirrors, Lord of Light, Stranger in a Strange Land, When the River Runs Deep
