Firefly

A firefly distal not east but west,
Encased in white crystals it safely lands,
It's light is divinity, a taste of the past,
A halo is given and lays on the sand,

A butterfly withers right under the sand,
In strange tounges it whispers "let go of my hand"
It's black and defected as it slowly ends,
A fun thought persisted "that light was my nest"
