Okay so there's a song that plays a lot in the DIC Dub during a ton of sad/redemption moments. 

Example: When Prince Endymion and Princess Serenity die: minute twelve

In the "Last Resort" episode where the spirit of the lake is purified and goes to rest.

Most of these are versions of the theme that I'm looking for - sometimes lighter, sometimes including the castanets from Tuxedo Mask's theme -- I'm pretty sure it's just his theme slowed down on piano instead of with horns but i can't find it anywhere and as the skype chat can confirm its driving me crazy.

 please help if you can. 

I found it in midi form on an old site; they called it "Downfall of the Silver Millennium" or "Silver Millennium Downfall" (direct midi link) but that name isn't picking anything up on other search engines @.@

FOUND IT! YAAAAAAAAAAAAAAAAAY

I know that this youtube channel has a bunch of unreleased dic cues, but it doesn't have the song you're looking for. I did find a compilation vid of DIC songs, and am trying to find it atm.

Kyra! I think I have an MP3 version of that BGM! I can send it to you over skypes. ;D
