Lyric discussion by Bug2 

For some reason, this song reminds me of the Smashing Pumpkins song Today.

Etymology:From Old French soverain

Souverain= french used as noun or adjective = sovereign= Exceptional in quality.

Of course...he just could have made up the word because it sounded right too. (smirk)

Souverian is a first name (and is used as such in the song). But your etymology there may explain why he picked it for this song.
