What has many keys but can’t open a single lock?

Flying high in the sky, I entertain those who watch me, I ward off ghosts, I honor ancestors, I am used for air battles, or I am just a toy.

An amber essence, worthy of all living on Earth's sod. I am crafted with machines who were put here by God. I am immortal. Born from laboured love to be total. Only miniscule amounts to a life of my creator, the span of birth to death. Most people separate the makers with a choropleth.

You fill me up when you are feeling low, but I’m empty when you are ready to go.

At a days ending, I give you a ring. I have always been a most sought after thing. I wear gowns, but when changed, all is off with a fling. In a frame, I lie naked, on a box full of springs.
