A Husk is the living environmental suit used by a Skin to survive on Earth. The husks are a parasitic lifeform technology that are genetically manipulated to resemble human beings. Husks begin as spores and take about 20 years to mature and harvest for use. A husk lives for about 50 years before degrading. A flap of skin at the small of the back conceals the suit's seal. If this seal is broken, the husk crumbles into dust.
