Every prison takes its certain shape. Some cages are gilded, some barren, some empty and dead. Some exist in wilderness, in solitude under the open sky. Some are clear, others not so much. A lifetime spent without purpose. A purgatory awaiting death. A sentence suspended. Painful care taken at every turn.

What scared us so fucking bad, and was so dangerous that we evolved to be afraid of almost, but not quite human creatures?
