I think sun vs. Son makes sense given the background. Sun rising to find a new day and peace in the future.

Out of Wikipedia - background behind Soon:

"The Gates of Delirium" is a 22-minute track that Anderson described as "a war song, a battle scene, but it's not to explain war or denounce it, really ... There's a prelude, a charge, a victory tune, and peace at the end, with hope for the future."[7] Moraz recalled discussing War and Peace and Leo Tolstoy with Anderson as they both read the book, after which Moraz showed Anderson a French science fiction comic book with "Delirious" in the title. Moraz said, "he related to it immediately so I think that perhaps as a title 'The Gates of Delirium' came from that".[10] Anderson and White stopped by a scrap yard and bought metal car parts which were used as percussion during the song's battle section.[11] During the battle section, White formed a tower of the parts and pushed it over to make a crashing sound. The track concludes with a gentle melody and a lyrical prayer for peace which later became known as "Soon".
