This piece is for the following scene from the last part of section 25 of Part IV:

"Enna nods to herself, finding peace in her mourning. She has an inner monologue, making an oath to the memory of Syne and what he stood for. She now must move on, returning to an uncertain world, where there are many new dangers and a hazy future. She grips the hammer-pick firmly in her hand, growing confidence in their actions and in the choices she's made. A tear streaks down her face, and she leans back against Rush. Slowly she finds sleep while a subtle smile dances on her lips. The sky darkens, and the dragon flies on."

Really? Well I agree with the brass at the beginning but for the rest of the song I thought I had put a noble yet soft and sad feeling to it because from what I gathered, Syne took his life to save the lives of others and Enna is mourning over, and reflecting on, Syne and what he stood for. I guess that's the music that resulted. I can't be certain, though. I guess more perspectives would help...maybe I should add a proper introduction...
