Answer:
I am a type of cheese made backwards
I do not contain flesh feather or scales; yet I have fingers and thumbs.
I reach for the sky, but clutch to the ground. Sometimes I leave, but I am always around. What am I?
I can sizzle like bacon. I am made from an egg. I have plenty of backbone but lack a good leg. I peel layers like onions but still remain whole. I can be long like a flagpole yet fit in a hole.
I am the beginning of eternity the end of time and space the beginning of every end the end of every place.
Dark, feathery, and popular in Baltimore and fantasy books.
