I made a playlist for The Wyvern! It's on 8tracks and on YouTube. I'm having trouble posting the 8tracks link, but if you go to the 8tracks website, and search for "The Wyvern", you should find it. It's made by emmagnetised, and it's got 22 tracks.
It's made up of things I've listened to while writing, songs that remind me of certain characters/scenes/relationships, and the odd song a reader has suggested. I've included annotations about why each song was chosen, I'd recommend giving those a read.
