<div class="quoteheader"><div class="topslice_quote">Quote</div></div><blockquote class="bbc_standard_quote">The Black Carapace, also known as the Interface, is the last and one of the most important of all the 19 gene-seed organ implants a Space Marine Neophyte will receive as he is transformed from a normal, adolescent human male into a superhuman Astartes. This neuroreactive, black organic fibrous material is implanted directly under the skin of the Neophyte's torso. Points are then cut through the Carapace by an Apothecary using surgical tools allow a Space Marine to directly interface his cerntral nervous system with his Power Armour's cybernetic systems. After a few hours, the material hardens and invasive fiber bundles that serve as neuron connectors grow inward and interlink with the newborn Astartes' central nervous system. Note that a Space Marine needs the Black Carapace to use his Power Armour to its maximum capabilities, but the armour itself does not need this implant in order to function.<br/></blockquote><div class="quotefooter"><div class="botslice_quote"></div></div><br/>Mechanically, it allows you to wear power armor without the Hulking size trait, and is also required to wear Astartes-grade power armor.<br/><br/>Fluffwise, it must be implanted before age 18, or at least 'seeded'. So he's got bits of the Carapace under his skin somewhere, though it won't grow to cover his entire torso until he has the full procedure done.
