Huerm...Oh dear. Music...
Liallia-
The Poet and the PendulumProbably because of the lines/ stanzas: "Oh Christ how I hate what I have become..."
"My home was there 'n then
Those meadows of heaven
Adventure-filled days
One with every smiling face..."
And of course, because the song itself is simply beautiful by itself.
Zarya-This one was tougher, since I have done very little writing outside of roleplay with her, but I believe she could have the theme song of:
Wanderlust-Bjork Since she has left her past (origin) behind, and she wants to find a new life for herself.
Menefer-
Epiphany- Sweeney ToddIn all honesty, I partly built Menefer around this song. The magician that bound him to the physical planes has long died, after Menefer being convinced by an associate that waging war with the magicians would not be the smartest idea, and he vows his revenge on the magician. He is trapped, unable to go back to the planes of Essence, leaving behind his life, and loved ones. Even now he plots for necromancy...
Itotia/Makani- Huerm. I never really thought much about this combined duo. The only thing that comes to mind is
Riders on the Storm- The Doors, and probably because they always seem to be chasing after peace, never quite satisfied.
