I am a artificial lifeform known as a Xen. My body has been bioengineered to withstand harsh environments and large amounts of damage. I am the first of my kind to be created.... I am to learn all I can about serving and protecting the people that created me... I look exactly like my creators but my internal skeletal structure is made of a strong metallic composite material... My organs and blood are organically grown protected by a layer of damage resistant skin.
