Q u o t e:
I'm just wondering; are instrumentals eligible?

Good question! After reviewing the rules once more, it nowhere states the pieces must contain lyrics. If you can capture the feeling of any of our universes through the medium of instrumental melody, then go for it, and submit your piece! =)
