This is sweet EP! I'm thinking about what it means for him to move and I am wondering what you were envisioning. Are you thinking that the tree is walking around with him on the "Throne of Vines" as it were, or more of a "where ever he goes, his magical presence is so powerful that the earth sprouts tree after tree that carry him along like a conveyor belt?"
I'm hoping it's the latter, it's a cool image.
